How to Choose the Best Filter for Your Turtle Tank? What You Need to Know

best filter pump for turtle tank

There are many factors to consider when choosing the best filter for a turtle tank.

Before you go out and spend a lot of money at the pet shop, consider the following

External vs Internal Filter

Internal filters are cheaper and easier to setup than external filters.

For experienced pet turtle owners, an external canister filter is the way to go as they provide the best performance.

You can also use a combination, by adding both an internal and external filter.  

It all depends on your setup, including of course the size of your turtle tank and what it can fit.


The Motor

This part of the filter is also important, since there are a few things to consider.

Motors can be loud, but the good news is you can buy “quiet filters” which is great for tanks in small living rooms.

The motor takes on a heavy load, so make sure to buy a good quality filter with a reliable motor.

Motors can run for several months at a time with no maintenance if you invest wisely.

You can find cheaper filters that will require much more hassle and maintenance, so the choice is yours!


Filtration Mechanism

Water filters can use different methods of filter the water.

So make sure to check the type of filtration it uses and choose a suitable one for your tank  Types of filtration include:

1. Mechanical Filtration

best filter setup for turtle tank

These filters operate like a “strainer” and sift out chunks of food and dirt from the water.

Usually they will use a sponge or floss type mechanism to keep the water clean.  

Mechanical filters are basic, but get the job done.

2. Chemical Filtration

To clean the water completely, chemical filtration is one of the best options.

It uses compounds such as activated carbon to absorb any toxic or harmful chemicals from the water.

It’s a more thorough type of water filtration that will help keep your pet turtle healthier.

3. Biological Filtration

This type of filter uses a more natural approach to keeping the water clean by pumping more nitrogen into the tank to produce oxygen.

This will keep the tank water fresh and clean, making it a more pleasant environment for your turtle to live in.

Additionally, this type of water filter promotes healthy bacteria, creating a more natural ecosystem in the tank.


Tank Size

As you may already know, turtle tanks come in various shapes and sizes.

The most important thing you need to know is the liter or gallon capacity of your turtle tank.

Filters are usually designed for specific tanks, such as for 20 gallon or 40 gallon. They can also be adjustable and configure for several tank sizes.

Always make sure the read detailed product information so that you know exactly what kind of tank the filter will support.

You can use a less powerful filter on a bigger tank, but it will have to work harder and may affect the lifespan of your water filter, for example.  

Make sure to buy a water filter that will work with your turtle tank!
