Filter for the Red-eared Turtle: types, rating, specifications and recommendations


It is advisable to change the water in the terrarium or aquarium daily, but this is not always possible. Currently, there are various filters for aquariums. Using them, you can change the water once every few days.

Simple internal filters with sponges are best used in small aquariums. In shallow aquariums, these filters can be laid to the side so that they are completely immersed in water.

Simple filters allow you to trap large particles of dirt, and they can also act as low-power biological filters.

For spacious aquariums with a volume of 120-150 l, which contain adult turtles, filters that pump 8-10 volumes of water per hour will be required. For this, portable canister-type filters are suitable. They place filler (plastic or ceramic balls, pipe glasses or cubes). Such a filter quite effectively purifies water in aquariums.

To protect the filter tubes from damage by turtles, you can fence off a small area near the wall with a plexiglass partition, and the partition should not go to the bottom. Behind the partition, you can place not only the filter tubes, but also temperature sensors, as well as other devices.

In addition to filters that clean water from dirt particles, biological filters are now increasingly being used. The peculiarity of these filters is that they destroy nitrogen compounds dissolved in water with the help of bacteria that settle on a filtering material with a large surface, such as sand, gravel, plastic tubes or balls. You can purchase special filter media that are sold at pet stores. Biological filters allow you to keep water clean for a long time, but it is recommended that you change about a quarter of the volume of water in the aquarium once every 1-2 weeks.

Completely changing the water in an aquaterrarium equipped with a filter is sufficient once every 1-2 months. However, if the filter does not cope with the purification of water and it quickly becomes dirty, it needs to be changed more often. In addition, it is desirable to install a more powerful filter.

The water in the terrarium or aquarium with the turtle should be clean.

To speed up the filter, it is recommended to add special preparations that contain bacteria to the water. They can also be bought at pet stores.

A biological filter is usually a plate installed at the bottom with a large number of small holes, onto which gravel or coarse sand is poured with a layer of 4-5 cm, but for terrariums or aquariums containing turtles, this filter is not suitable. Turtles scatter sand when they swarm at the bottom, resulting in the formation of areas uncovered by gravel and allowing the filter to work. For turtles, it is best to build an artificial shore with gravel poured on top 5-6 cm thick as a biofilter, and a pump is used to circulate water in the pond. A safety net must be put on the suction port of the pump to prevent foreign objects from entering the pump.

At the inlet of the filter, it is recommended to install a foam sponge as a pre-filter that will trap dirt particles.

A dirty filter must be washed regularly, however, in no case should you use soap or detergent, it is best to wash it under a strong stream of warm water.

The biological filter filler should be cleaned only if it is heavily contaminated with clean water without chlorine so that beneficial bacteria do not die.

5. Feeding of red-eared turtles.

Under natural conditions, red-eared turtles feed on both plant and animal food. When keeping these animals at home, it is important to properly organize their diet so that it matches the natural value in terms of calorie content and the content of basic nutrients.

Trachemys living at home need a balanced diet, including all the substances they need.

In nature, the animal can independently find sources of vitamins and minerals for itself, but at home you should take care of this.

Trachemys are fed mainly animal food.

Small young turtles can be given bloodworms, tubule makers, dried daphnia, earthworms, concentrates intended for aquarium fish, dried or live gammarus (aquatic crustaceans).

Only with a properly composed diet will the turtle grow well.

Large adult red-eared turtles, in addition to the above feeds, can be given raw or boiled chicken, beef. Many experts instead of meat recommend giving the turtles raw lean fish, which it is advisable to hold for 1 min in boiling water before giving it to the pet, as it contains the enzyme thiaminase. Small fish can be given along with the bones, after grinding it.

In the diet of water turtles, it is imperative to include insects: mealyworm larvae, various beetles, etc. Pets will be happy to enjoy shrimp, squid meat, or raw liver.

These products, by the way, contain many vitamins and minerals necessary for turtles.

Many experts recommend feeding live-eared turtles, which they can catch on their own, as often as possible. This is another way to create a pet environment that is close to natural.

Some experts advise preparing a mixture of various feeds on the basis of agar-agar or gelatin with the addition of raw chicken eggs, vitamins and bone meal. It can be stored in the refrigerator and, if necessary, given to animals.

With age, red-eared turtles begin to feed not only on animals, but also on plant foods, mainly algae. To make the terrarium look neat, it is best to grow plants in a separate aquarium to feed the turtles.

Almost all algae can be given to turtles, with the exception of elodea and limnophiles, since they are poisonous.

Plant foods must be present in the diet of adult turtles.

If it is not possible to feed animals with algae, you can give them dandelion or lettuce leaves, slices of fresh cucumber, white cabbage: red-eared turtles eat them with pleasure. If there is a pond near your home, you can collect duckweed and other aquatic plants from its surface and give turtles from time to time.

It is convenient to use ready-made feeds for feeding red-eared turtles, which at present can be easily purchased at any pet store.

However, when buying them, it is important to pay attention to the composition and content of nutrients and vitamins. So, cheap finished feed consists mainly of gammamarus, bloodworms or tubule maker.

Experts note that they are not balanced enough, therefore, it is recommended to include the above-mentioned fresh products in the diet of turtles in addition to them. If possible, you should purchase expensive imported combination feed. Dry food intended for dogs and cats cannot be given to turtles, because they contain nutrients that do not meet the needs of reptiles.

Any feed should be fresh and of high quality. In no case should spoiled food be fed to turtles, and frozen food must first be warmed up to room temperature.

It is recommended that bone meal be added to food for red-eared turtles once a week, which is an indispensable source of calcium needed for skeleton and shell. Crushed egg shells or calcium gluconate are also suitable. In addition, it is extremely useful from time to time to give the turtle 1-2 drops of an oily solution of vitamin D.

Any food to turtles is poured directly into the water. Despite the fact that water turtles eat fast, pieces of meat or fish left in the water begin to rot and become unfit for food. Therefore, animals need to be fed exactly as much as they can eat in 15–20 minutes, otherwise it will be necessary to change the water in the aquarium after each feeding.

If there is time and desire, while feeding the turtles, you can remove it from the permanent terrarium and put it in another container, where to feed the feed. However, not every pet will like this treatment.

It is necessary to feed turtles during the day, as they are most active during daylight hours, despite the fact that for a long time they were considered nocturnal animals.

Giving animals food is recommended after they have warmed up enough, since turtles that have been in a cool place for a long time have no appetite. If it is not possible to feed the turtle during the day, it is best to give it food in the evening, a few hours before bedtime.

Young red-eared turtles are recommended to be fed once a day, and starting from the age of 2 a little less often, once every 2-3 days.

Turtles are animals that can go without food for a very long time, several days or even weeks, but you can not starve them.

Determining if a turtle wants to eat is pretty easy. Ruby-eared turtles, being hungry, restlessly inspect the bottom of the aquarium or terrarium in search of food, randomly moving in the water.

If the animal refuses food for a long time, it must be shown to the veterinarian, as this may be a sign of illness.

Often the turtle just bought does not eat, because it cannot get used to the new environment and unfamiliar conditions. In this case, the animal needs to be given rest and for some time not to touch it and not to make noise in the room where it is located.

Often the turtle’s lack of appetite is due to the fact that it cannot get used to the new diet. You need to find out what the tortoise was eating before it appeared with you, and gradually accustom it to new food. If you have other turtles, it’s best to plant a new animal right away, then it will start to feed with them.

In nature, red-eared turtles feed on plants and small animals.

When keeping several turtles in the terrarium, it is necessary to ensure that larger and stronger individuals do not oppress the weak and allow them to approach the feeding trough.

Turtles do not eat very carefully and scatter a significant part of the food and trample it in the ground, so the food should not be left in the corral or terrarium for a long time. The food can deteriorate, creating favorable conditions for the development of bacteria that cause diseases.

When feeding, it is necessary to remember that, having finished eating, after a while the turtle can return to the feeder, so you should not immediately remove the food.

Ruby-eared turtles need to be fed sparingly, because overeating them can only hurt. If the tortoise is full, it is not necessary to give it additional food.

6. Care for turtles.

Regular care is the key to your pet’s health. Subject to all the rules, red-eared turtles can live in captivity for up to 30 years.

One of the main principles of care for turtles is to keep them clean.

Turtles get dirty in the soil poured on the bottom of the terrarium or aquarium, food debris often sticks to the skin near the mouth, so animals should be bathed regularly, especially during molting.

The animal should be bathed in warm water with the addition of drinking soda at the rate of 1 teaspoon of soda per 1 liter of water. Water should be poured into a shallow bath so that the turtle’s head remains above the water. The first few minutes, the animal can be nervous and restlessly moving, and then it calms down and freezes for a while. Turtles prefer to defecate in water. You need to bathe a turtle only in a room with a temperature not lower than 23 ° C, otherwise it may catch a cold.

Take the turtle in your hands carefully.

The main hygiene procedure for all water turtles, including red-ears, is the removal of algae that has grown on the shell. It is necessary to clean algae very carefully, being careful not to damage the shell. Do not use hard brushes or sharp objects for this.

In winter, the turtle must be periodically irradiated with a quartz lamp. The lamp should be installed at a distance of about 1 m from the animal and irradiated for several minutes, making sure that the rays of the lamp do not fall into the eyes of the turtle.

The duration of exposure should be gradually increased from 30 seconds to 5 minutes. Conduct radiation sessions should be every other day. After a series of sessions, you need to take a break of 10 days, and then continue irradiation. In the summer, sun baths have a positive effect on the health of turtles.

After any contact with turtles, wash your hands thoroughly. In no case should you wash the terrariums, aquariums and food bowls in the kitchen.

Many ignorant lovers believe that for all types of turtles at home they need a period of hibernation. However, this statement does not in any way apply to red-eared turtles. Turtles are cold-blooded animals. They hibernate when the ambient temperature becomes too high or too low to support the vital activity of their body (for red-eared turtles, these indicators are respectively 40 and 10 ° C).

Irradiating water turtles with ultraviolet lamps is a must on land. It is best to remove them from the terrarium or aquarium and transplant them into another container for the duration of the irradiation session. You can irradiate them in the terrarium during the replacement of water.

While maintaining a constant temperature in the terrarium during the cool season, red-eared turtles will feel fine even without hibernation.

It is especially necessary to dwell on the mistakes made by inexperienced lovers of red-eared turtles when caring for them, and their consequences. The most common are the following.

1. Terrarium for the red-eared turtle is not spacious enough. As a result, her movements are limited.

2. The land plot is not equipped in the terrarium, and the water level is too high. As a result, the turtle can drown.

Trachemys with pleasure are chosen on land.

3. The constant temperature in the terrarium is not maintained. The tortoise becomes lethargic, and in the winter in the absence of heating it can become sick.

4. The nutrition of the red-eared turtle is not balanced (either only meat or only vegetable feed is given). Because of this, the pet may develop metabolic disorders, the turtle will not develop properly.

5. There are not enough vitamins and minerals in the feed of turtles. As a result, vitamins develop in animals, and reproductive ability decreases.

6. Irregular measures are taken to clean the terrarium (water rarely changes, the remains of feed and excrement are not removed). As a result, a favorable environment is created for the development of pathogenic bacteria; algae appears on the shell of turtles.

7. Reproduction of turtles.

Turtles in captivity breed quite rarely. Breeding turtles is a painstaking and responsible work that only experienced specialists can use.

In order for the turtles contained in the house to breed, you need to provide them with the proper conditions: proper nutrition, a suitable habitat and relative freedom of movement.

For successful breeding, in addition to observing all conditions of detention, it is desirable to place several individuals of the same species in one pen or terrarium. When forming a group, the correct ratio of the number of females and males is important, which contributes to the manifestation of elements of mating behavior in these animals. In freshwater turtles, this ratio is approximately 2: 1.

Only with proper maintenance, red-eared turtles can give birth in captivity.

In addition, when choosing animals, you need to take into account their age - you should select sexually mature, but not old individuals, which should first be checked with a veterinarian. The most suitable age for mating red-eared turtles is 5 years. Despite the fact that puberty occurs in them a little earlier, fertilization in too young individuals may not occur. Sick or weakened animals are also unlikely to produce offspring.

One can distinguish the gender of red-eared turtles by the length of the tail (in the male it is longer). In addition, the male on the plastron has a recess.

For a while, a group of selected turtles needs to be carefully watched to determine how ready they are for mating games and breeding. If a relationship has been established between heterogeneous individuals, the remaining turtles need to be moved to another place.

Usually, lovers breeding red-eared turtles in captivity contain males and females separately, and they are planted with each other exclusively for the period of mating. In this case, the male is best left on the territory familiar to him, and the female is placed to him.

It is interesting to watch the mating games of turtles both in natural conditions and at home. Turtles often during the breeding season manifest themselves on a completely different side than in ordinary life. So, males often fight among themselves, seeking the favor of their chosen female.

Offspring can give only healthy turtles that have reached puberty.

If you want the turtle to produce offspring, include vitamin E in its diet. It has beneficial effects on reproductive function.

Turtles, like other reptiles, after building a nest and laying eggs do not care about offspring at all, and small turtles appear already completely ready for independent life.

In preparation for breeding, it is important to correctly formulate a diet of turtles. Many experts recommend adding foods containing vitamin E (greens, vegetable oil) to animal feed. Vitamin preparations are also suitable.

During pregnancy, in the diet of turtles must be present foods with a high content of calcium and phosphorus.

During the breeding season, red-eared turtles need to create comfortable conditions: do not disturb them, exclude all extraneous noise and vibration, and try to touch animals as rarely as possible. In addition, you must take care of the place where the eggs will be placed in advance. Trash-eared turtles dig a nest in the ground, so in advance you need to put a small container filled with clean sand or peat in the terrarium (it should be poured with a layer of about 5 cm). Females can also lay eggs directly on the land plot arranged in the terrarium, and sometimes in the water. In the latter case, it is recommended to immediately remove the masonry from the water.

Tortoise laying eggs

For freshwater turtles to start mating games, the water temperature in the terrarium or aquarium should be 22–26 ° С. Also, increase the duration of daylight and the intensity of lighting helps to stimulate mating.

After the female lays eggs, a container with them is recommended to be removed and placed in an incubator. The temperature in the incubator should be maintained at 28-30 ° C.

If you do not have an incubator, you can use a regular glass jar or aquarium filled with sand, which should be regularly moistened. Such an incubator can be heated using a conventional incandescent lamp. You can put the incubator next to the central heating battery.

The eggs of turtles, unlike birds, cannot be turned over in any case, therefore they should be transferred very carefully to the incubator.

The appearance of a baby turtle from an egg

Eggs laid by turtles are far from always fertilized. In order not to keep empty eggs in the incubator for several months, they need to be checked. To do this, you can build a primitive ovoscope: put a small light bulb in a small cardboard box, you can use a flashlight from your pocket, and cover the box with a lid, in which an egg-shaped hole is cut, but a little smaller. To test an egg, you need to put it, without turning over, into the hole and turn on the light bulb. In the middle of the fertilized egg, dimming will be noticeable, and the empty one will transmit light evenly. When checking, you should remember that the longer the maturity of the eggs, the more accurate the result.

Newborn baby turtles, like other reptiles, have the remains of the yolk sac, which disappear a few days after birth, as well as a special egg tooth with which they dissect the shell. In addition, in the first days after leaving the eggs at the turtles on the plastron, you can see a transverse fold - a consequence of the bent position of the cub inside the egg.

After the female lays eggs, she should be kept away from other animals for some time. Female nutrition for several weeks should be enhanced, since during this period the immunity of turtles is weakened and they are more susceptible to various diseases.

If the turtle has cubs, you need to try to save them all. In no case should they be placed in the same paddock or terrarium with adult turtles, as these reptiles have no maternal instinct and can harm cubs. It is best to prepare a small separate terrarium specially equipped for their maintenance.

Little turtles need special care.

Small turtles feed in much the same way as adult turtles, with the exception of plant foods. They are suitable for both special ready-made food, and finely chopped raw fish or pieces of seafood.

For normal development, young red-eared turtles need ultraviolet radiation. The exposure time should be increased gradually, starting from 1-2 minutes, and soft light bulbs should be used for the procedures.

8. Prevention and treatment of diseases of turtles.

Like other pets, red-eared turtles can get sick. Unfortunately, this cannot always be avoided, but many diseases can still be prevented by conducting simple preventive measures.

In nature, red-eared turtles are distinguished by fairly good health, but at home they need constant attention and good care, since they live outside their natural habitat.

In many ways, the health of a turtle depends on the minerals and vitamins it receives with food. The lack of necessary elements leads to various developmental disorders, diseases and even death of turtles. Far from always, the products that the home turtle eats contain all the necessary substances, so it is recommended that she add special vitamins to her food to prevent health problems, because it is always easier to prevent the disease than to treat it.

The effect of vitamins on the health of turtles.

No animal can do without vitamins.

Reptiles, including red-eared turtles, are no exception. Below we consider the importance of individual vitamins for the health of turtles, as well as symptoms indicating a lack of any vitamin in the body.

Water turtles: water filtration

In most cases, maintaining a certain water temperature is necessary. Usually, ordinary water heaters are used for this, which are used for aquariums with fish. However, we repeat: turtles, unlike fish, can break heaters and be at risk of electric shock. It can be dangerous for a person if he puts his hand in the water. Therefore, if possible, heaters with a metal shell should be used or made inaccessible to animals.

Heaters are usually used only in aquatorrariums with sufficient water depth. They are not suitable for semi-aquatic species in aquaterrariums; it is best to use thermal mats or thermal cables in them, which are laid under the bottom of the terrarium outside.
In any case, now there are many companies that produce products in this area - there is a wide selection that helps to provide the necessary conditions for any terrarium.

As for temperature indicators, for the most common in our country, the Red-eared Turtle (Trachemys scripta), the water temperature should not be lower than 26 - 27 ° С. For some other species, the temperature needs to be selected individually, but for most tropical turtles this temperature will also be quite comfortable.

For aquatic turtles, the same type of illumination is suitable as for terrestrial species. Repti-Glo and Vita-Lite lamps are suitable for all turtles. The intensity of such lamps is selected depending on the species, but usually with a sufficient amount of calcium and vitamin D3 in the diet, high levels of ultraviolet radiation are not required for aquatic turtles.

Small internal filters. Filters for small aquariums are usually quite standard. They consist of a cylinder with foam rubber or similar material through which water circulates. Usually these are autonomous immersed water canisters that include a pump and a filtration unit in one unit. Standard flow rates range from 150 liters per hour to more than 400 liters per hour. The internal filling of such a filter must be washed regularly. Larger models require less frequent flushing than small ones. True, it should be noted that such a filter purifies water very mediocre. When using it, a frequent change of water is required, since it has practically no effect on its chemical composition.

If such a filter works under anaerobic conditions, then it will quickly clog and an unpleasant odor will appear. This type of filter is not very suitable for use in aquatorrariums where large animals or many small ones are kept, since the ability of such filters to work with a large amount of organic waste is extremely limited. These filters can be used quite successfully together with another layer (for example, gravel). In general, small filters are not quite suitable for use when it comes to turtles, although the best models can come in handy when growing young animals.

Outdoor filters.
For large volumes of water, external filters are more suitable. They usually consist of a large cylinder with separate layers of filter material, varying in function. For example, the initial level may have a fine mesh to capture large particles, followed by a thinner layer of foam and a layer of polyester to trap smaller particles. This type of filter can also be equipped with activated charcoal, which can remove dissolved organic compounds, some proteins, lipids and chemicals (such as chlorine).

External filters must be positioned below water level to ensure proper pump operation. They are installed in the supplied stand below the aquarium. These filters are very useful for medium-sized aquariums, where one filter is used for one aquarium. In addition, it can be used in conjunction with secondary biofiltration to improve water quality.

You can also create complex designs from several filters that can maintain the purity of water in large volumes.

The basic principle of biological filtration. Biological filters fulfill their functions by accumulating millions of living bacteria. Biofilters remove toxic nitrogen waste from water. Turtles produce urea or uric acid, which, under the influence of bacteria, turns into ammonia. This process is called nitrification. Bacteria such as Nitrosomonas and Nitrobacter perform nitrification. These bacteria metabolize nitrogenous products to produce energy. The presence of oxygen is very important for nitrification.

A biological filter contains several essential components: there must be an appropriate substrate for colonizing bacteria, there must also be a sufficient flow of water through the substrate to supply it with oxygen, which supports the activity of aerobic microorganisms.

The flow of water through the filter should be carried out slowly enough so that bacteria can carry out the process of nitrogen absorption as productively as possible. However, if the speed is too slow or the flow of water stops completely, the filter will become anaerobic and begin to generate ammonia instead of absorbing it. In such cases, nitrifying bacteria die and are replaced by other species.

Most types of anaerobic bacteria emit toxic by-products, both inorganic (hydrogen sulfide) and organic (biotoxins). As a result, the water in the aquarium can produce an unpleasant odor and be poisonous to living things.
Various materials are used as a substrate for nitrifying bacteria, most often gravel. You can also use sand and porous ceramics.
Large outdoor filters can combine both mechanical and biological filtration.

Chemical filtration, activated carbon and zeolite.
The term "chemical filtration" means that impurities are removed from water by chemical means. Typically, the chemical agent involved in the filtration is located in the second chamber in non-biological systems, and the first contains some kind of mechanical medium. A typical combination is a foam filter as a mechanical medium and activated carbon as a chemical agent. Activated carbon removes ammonia and other impurities through adsorption.

Coal is activated by heating to a very high temperature. This opens up millions of pores, which represent a large surface area for chemical adsorption. When the entire surface area is filled with impurities, it is necessary to change the coal. Due to its limited capabilities, activated carbon is only suitable for small-sized aquaterrariums - not more than 500 liters.

In small and medium volumes with turtles, one of the best methods for using activated carbon is to combine it with gravel as the mechanical part of the filter. The large external filter is almost completely filled with gravel for basic filtration, plus an external filter of the Fluval ® type is also used, 80% filled with activated carbon and 20% with foam. This combination works great.

For large aquariums, it is preferable to use zeolites. Zeolite is a hydrated aluminosilicate of calcium, sometimes sodium and potassium. As with most other filtration materials, the larger the surface area of ​​zeolites in water, the more efficient the filtration process.

The main advantage of using zeolites instead of activated carbon is that they can be refined and reused. The chemical bond between zeolites and ammonia is weak and can easily be broken by the addition of salt water to the substrate used. The procedure is as follows: put the used zeolites in a container and add a saline solution made from 6 g of salt per 1 liter of water, keep them in it for 24 hours. Wash the zeolites completely in fresh water before reuse.

Zeolites can be added in separate layers to an existing filter system. Although this method is recommended quite often, in reality it is not a particularly effective way to use this material. It is much more efficient to use zeolites in a separate chamber filled with them completely.

Warning: zeolite filters must be disconnected every time any therapeutic measures are carried out in the aquarium. Zeolites will be destroyed if substances such as malachite greens, acriflavine or other disinfectants come into contact with them.

Types of filtering devices

Both external and internal cleaning devices are divided into five types:

  1. Mechanical. The simplest filter, it is made of a motor and a suction tube with a piece of foam inside. Suitable for small fish tanks.
  2. Chemical. This is a filter in which a filler such as an adsorbent is used. Most often, coal is used for this. Such devices are more suitable for terrarium with turtles than mechanical ones.
  3. Biological. In this filter there is a special compartment in which beneficial bacteria multiply. They have a positive effect on the water in the aquarium, further purifying it.
  4. Combined. A universal filter that combines different devices.


The internal devices for aquariums, as a rule, are a plastic container with side openings through which water enters. Inside are installed cartridges with filter media, most often a sponge. After time, beneficial bacteria grow in it, and the filler begins to work as a biological filter. At the top of the device is a pump with a diffuser. She pumps water and saturates it with oxygen.

You can install such filters for red-eared turtles in any position both horizontally and vertically. This allows you to place them in shallow aquariums. When purchasing an internal device, it should be borne in mind that you need to install the filter in a separate compartment, since water turtles can easily bite through the tubes.

Many aquarium owners complain about the poor performance of internal filtering devices. This often causes them to quickly become clogged. Internal filters for red-eared turtles, as a rule, are placed in small aquariums with a volume of 50-100 liters, which are intended for medium-sized animals.

In order to get around all these shortcomings, lovers of aquatic animals should get an external device. They are especially suitable for owners of large turtles with a shell length of 10-15 centimeters.

For such amphibians, a capacity of more than 120 liters is needed. When purchasing an external filter for red-eared turtles, it should be borne in mind that its production should be at least 8-10 volumes of the aquarium per hour. Externally, the device resembles a canister. Water is purified in a container that looks like a tank, and it is attached to the outside of the aquarium. Water is pumped from the terrarium to the filter and vice versa thanks to the pump, as well as the outlet and intake plastic pipes.

Inside the external filter for the Red-eared Turtle there are several compartments for various types of fillers, which perform the function of cleansing. They also reproduce bacteria that provide biological treatment of water. Through the intake pipe, water is taken from the tank. Then it is run through the filter itself with the appropriate fillers, and the already enriched with oxygen and purified liquid is poured back into the aquarium.

Pros of an external device

The external filter for the water-eared turtle eared water has the following advantages:

  1. The device saves space, in addition, it does not spoil the design.
  2. Animals cannot break the filter and injure themselves (except in rare cases).
  3. External filter is easy to maintain. It is washed no more than once a month, and in some cases once every three months.
  4. An external filtering device for the aquarium creates a flow of water, mixing it and saturating it with oxygen.
  5. A large number of bacteria develop in the fillers of such filters, which provide biological purification of water from waste products living in the aquarium of animals.

Manufacturers Rating

For the first time when faced with the purchase of a filtering device for most lovers of aquatic turtles, the question arises: “Filter for which red-eared tortoise is worth buying?” Below is the rating of the most popular manufacturers with customer reviews.

Atman is a Chinese brand. It is believed that the company produces the best Chinese filters. Devices are manufactured in the same factories where JBL and other popular filters are being assembled. Many aquarists have tested the CF line, which leaves a lot of positive feedback. The DF line was created in conjunction with JBL. The devices are fully operational and equipped.

Aquael is a Polish manufacturer. Here it is worth paying attention to the models UNIMAX 250 (650 l / h for aquariums up to 250 liters) and UNIMAX 500 (1500 l / h for aquariums up to 500 liters). The advantages of the devices are the built-in mechanism for pumping air out of the tubes and the filter, the fillers in the kit, the function of adjusting the performance, and they are also very quiet. Consumers leave negative feedback about the following company filters:

  • Aquael UNIMAX 150 (canister, 450 l / h) - may leak from under the lid,
  • Aquael Unifilter UV (500 l / h) - poorly cleans water.

Eheim is a well-known manufacturer. The company makes expensive, but very good devices. The brand is considered the best in terms of noiselessness, reliability and quality of water purification.

Hydor (Fluval) manufacturer from Germany. Fluval filtering devices are available in the lines 105, 205, 305 and 405. In the negative reviews it is mentioned: grooves, weak clamps, rubber bands require lubrication. Of the successful models, you can select the FX5, but it is more expensive.

JBL is another German manufacturer. Two filters are worth highlighting here: CristalProfi e900 (900 l / hr for aquariums of 300 liters) and CristalProfi e1500 (1500 l / hr for tanks of 600 liters). Devices are ready to use and are fully equipped. These filters are positioned as reliable and practical. In addition, they have a modern design. Of the minuses, only a complaint is noted about a very tight pumping button.

Jebo is a Chinese manufacturer. Devices for filtering water in the aquarium of this brand have many positive reviews: the degree of contamination is visible, copes well with the cleaning function, the lid is conveniently removed.

Tetratec is a German company. The manufacturer has two models of filters that you should pay attention to: EX700 (700 l / h for aquariums of 100–250 liters) and EX1200 (1200 l / h for aquariums of 200–500 liters). The devices are fully operational and equipped with filter materials and tubes. In these models there is a button for pumping water, which facilitates the start. The reviews indicate the quiet operation of the filters and good equipment. Of the minuses: in the early 2000s, the company released a series of defective devices (loss of power and leakage), which greatly spoiled its reputation. Currently, everything is in order, but buyers still look at the filters of this brand with caution. When servicing these devices, it is recommended to additionally lubricate the rubber bands for sealing in order to avoid unpleasant situations.

ReSun is a Chinese brand. Has the worst reviews. The filter has a weak plastic - it can last a year and leak. Experts do not recommend purchasing devices from this manufacturer.

How to mount the internal filter device

The internal filter for the aquarium for eared turtles is installed as follows:

  1. To start, the aquarium is half filled with water.
  2. All parts of the filter part are dried before assembly.
  3. The device is immersed in the aquarium from the opposite side of the turtles (at this moment it should not be connected to the outlet).
  4. Using suction cups, the device is attached to the walls of the terrarium, while the filter should not touch the bottom.
  5. Tubes for air intake are brought out.
  6. After doing all the procedures, the device is plugged into a power outlet (a flow of water should appear).

The external filter for the aquarium for red-eared turtles is installed as follows:

  1. The ends of the hoses for the release of water and its intake are lowered in opposite directions of the aquarium.
  2. The device is filled with water for the aquarium: for this, the water intake pipes are connected to the threads on the filter cover, then the tap opens and water is poured.
  3. An outlet hose is attached to the device, and water is poured through the free end, after which it is attached to a plastic outlet in the aquarium.
  4. After the manipulations are done, both taps on the filter open at once, then the device can be plugged into a power outlet (water will begin to mix).

It should be noted that any filter for rubella should be cleaned once every 1-2 months, since these amphibians leave an abundance of waste in the habitat. Do not use detergents to clean the aquarium itself.
