Best Filter for Turtles

A filter is necessary to keep the aquarium, turtle tank, or pond of our turtles in good condition. The water quality of the aquaterrariums is very important so that the aquatic turtles grow strong and healthy in their habitat. The water turtle filter perform the filtration and oxygenation of the water. Next, we will analyze a series of turtle filters showing features and ratings.

Turtles do not need to maintain water quality as optimal as fish but they do need a filter since turtles produce a lot of waste and stagnation would cause unhealthy water conditions. The turtle food also breaks down in the water along with waste, producing ammonia which is highly dangerous for turtles. To eliminate these toxic elements for our turtles, it is important to choose a good filter suited to the needs of our aquarium, pond, aquaterrarium, or turtle tank, maintaining a healthy bacterial colony responsible for converting ammonia into nitrate.

The choice of water filter for turtles is influenced by three factors: Capacity of our aquarium, space y budget.

The Best Filters for Turtles

Here are the best options we have evaluated for buying a turtle filter:

Types of Filters for Turtles

There are several types of filters for turtles that can be used in aquariums. We classify them filters into: internal, external, cascade y pond.

Internal filter: It is placed inside the aquarium and uses a pump to send water through a mechanical and biological filter before returning it to the aquarium. It is more suitable for small aquariums. They tend to be less powerful than others and have less filtration capacity.

Cascade filter: This filter is placed at the back of the aquarium and uses a pump to send the aquarium water through a mechanical and biological filter before returning it to the aquarium. They are easy to install and maintain. Also called backpack filter because of its backpack-like attachment on the aquarium.

External filter: These are placed outside the aquarium and connected by tubes to the aquarium. External filters contain a mechanical and biological filtration system, as well as a pump that draws water from the aquarium and sends it through the filter before returning it to the aquarium. External filters are ideal for large aquariums and usually offer high filtration capacity and easy maintenance. Within this type of filter, we find canister filters which are homemade aquarium filters.

Pond filter: It is similar to external filters, but they are specifically designed for use in ponds or large aquariums. They generally have a much higher filtration capacity than conventional aquarium filters and can handle large volumes of water. They have more filtration stages including the basic ones, such as mechanical, biological, and chemical filtration, and may include additional features like algae removal, water oxidation, and sterilization through ultraviolet light.

Next, we show how to choose the best filter for turtles:

Internal Filters for Turtles

They internal filters are those that are placed inside our fish tank or aquaterrarium. They generally have lower capacity for filter media and lower filtering power in liters per hour. These filters are initially recommended for small aquariums or turtle tanks with a maximum capacity of 50 liters of water regardless of what the manufacturer says.

Cascade Filters for Turtles

They cascade filters or backpack filter are external filters that hang on the aquarium, tank, or turtle enclosure producing a water fall that oxygenates the surface. They are generally filters for turtle tank more powerful than internal ones and have a greater capacity for filter media. They are very useful when you don’t have space to store an external filter. However, the downside is the noise caused by the water falling on the surface, which can be minimized by keeping the water level at the height of the water fall of the turtle tank filter. It is very beneficial to have a cascade filter in aquariums, fish tanks, turtle tanks of 35 to 150 liters.

Canister Filter for Turtles

The bucket filter is a type of external filter handcrafted from a bucket or container where the water is filtered through the installed filter media. Water circulates through the bucket filter thanks to the installation of a water pump or power head which draws water from the pond or aquarium. Afterwards, the water flows back into the turtle aquarium or pond by gravity.

How to Make a Bucket Filter for Turtles

There is the option to make a homemade turtle filter. Here we show a basic guide to making a bucket filter for turtles:

Required materials:

• A large plastic bucket
• A water pump or power head
• Plastic tubing or hose
• Filter material (sponges, filter cartridges, rock wool, etc.)
• Waterproof adhesive tape

Steps:

1. Cut a hole in the plastic bucket in a position that allows connection of the air pump and tubing.
2. Connect the air pump to the plastic tubing using waterproof adhesive tape.
3. Fill the bucket with filter material, making sure to cover it completely.
4. Connect the plastic tubing to the turtle tank and position the bucket so that the air pump is below the water level.
5. Plug in the air pump and adjust the speed to ensure proper water circulation.

It is important to remember that the bucket filter must be clean and regularly maintained to keep it effective. It is also important to select an appropriate filter material and an air pump with adequate capacity for the size of the turtle tank.

Making a bucket filter for turtles is a simple project that can help keep the water in the turtle tank clean and healthy.

Water Pump for Bucket Filter

A water pump is an essential component for a turtle bucket filter. The water pump is responsible for circulating the water through the filter material in the bucket and returning it clean to the turtle tank.

When choosing a water pump for a bucket filter, it is important to consider the size of the turtle tank and the amount of water that needs to be filtered. It is advisable to choose a water pump with a capacity suitable for the tank size and with the ability to adjust the water circulation speed.

How to Choose a Filter for a Turtle Tank?

As we have already explained, first decide what type of turtle tank filter we want (external, internal, or waterfall filter) based on our needs. We must consider, turtle tank size, where to place my filter, type of filtration (mechanical, chemical, and biological) to choose the filtering volume capacity y ease of cleaning of the filter.

The comparison tables showing the features of water turtle filters highlight the most important aspects to consider when choosing.

The Golden Rule: Power

The number one mistake is buying a filter that’s just right. For turtles, you need to oversize.

• The 3x Rule: The filter must have the capacity to 3 times the water volume of your aquarium.

  • Example: If you have 100 liters of water, buy a filter designed for 300 liters aquariums.

• Flow Rate per Hour: Look for a filter that moves at least 4 to 5 times the total amount of water per hour.

  • Example: In a 100-liter tank, the filter should move 400-500 liters/hour.

Where to Buy Filters for Turtle Tanks or Aquariums?

The best stores to buy the water turtle filters are:

• Online: If you want to buy a filter for your turtle online, shopping on the internet offers the widest variety and is your best option. We can get all types of internal, external, and cascade filters. It offers the best prices and shipping for your filter.
• Local store: The nearest local store or one you trust is the other option. Also, they might help you choose your filter as we show you in this article.
• Kiwoko: If you are looking to buy a turtle filter at Kiwoko, you can visit their website and check the aquarium and turtle section. There you will find a variety of turtle filter options, from internal to external filters, depending on the type and size of your aquarium.

Filtration Stages

An empty filter only moves water. To clean, it needs three types of materials. Make sure the filter you buy has space for:

1. Mechanical (Sponges/Polyester): Traps solid waste (feces, food remains). It is the first barrier.

2. Biological (Ceramic rings / Bio-balls): This is the most important! This is where the good bacteria live that eliminate ammonia (turtle urine), which is toxic. Never wash this with tap water, only with water from the aquarium itself.

3. Chemical (Activated carbon): Optional. Removes odors and yellowish color. It should be changed every month because it stops working.

Pro Tip: Many cheap internal filters only come with a sponge. That is not enough for an adult turtle. Look for one that has a compartment for ceramic rings.
