Turtle Filter Buying Guide

A turtle filter is a piece of science. It is a systematic device that follows specific processes for it to function adequately.

Therefore, there are important aspects of it that you should pay attention. In this way, you'll get a filter that can serve your needs and preferences. Here are they:

Aquarium Size

Before the filter, you should think about your aquarium first. Specifically, you need to gauge its size.

Through this, you will determine if you will need an external or internal filter. Obviously, an external screen is for large setups. But a large aquarium can house an internal filter as well!

Filtration Mechanism

There are three types of filtration that a turtle filter can provide to you. Here are they:

Mechanical Filtration

This process involves straining solid dirt like food leftovers. A filter that uses this technique comes with a filter floss or a sponge that takes out these stuff by screening them.

Biological Filtration

Biological filters optimize nitrogen cycle through the use various media that boosts oxygen generation.

As a result, the aquarium becomes a comfortable place for your turtles and other marine creature. The proliferation of healthy bacteria is also a by-product of biological filters.

Chemical Filtration

Filters like this are using the power of absorption to expel any harmful compounds and chemicals that are not seen by the naked eye. Media like activated carbon are often utilized here to cleanse the water.

Specifically, activated carbons have porous properties, making them efficient in the absorption of chemical residues.

External or Internal Filter?

We all know that external filters (e.g. canister filters) have powerful performance. But at the same time, they are quite expensive as well.

Meanwhile, it is undeniable that internal filters are cost-efficient. As its name suggest, you can install an internal filter inside the water tank. Alternatively, you could also mount it to the side panels.

You can use both of these filters on a turtle tank. Just take note of the size of your aquarium. If it is big, then you should go for external filters. You could also use external filters that can operate on low water levels as well!

Aside from these considerations, you should also consider your budget and preferences. Choose a unit that is acceptable to means and needs. In this way, you can get a functioning filter that wouldn't give you a headache.

And if you are looking for quality filters for your turtle tanks, then you should check out these following products.
