Because of their small size, small fish tanks require a small fish tank filter and a great deal more maintenance than a larger fish tank. 

This is due to the fact that toxins can build up in a small tank much faster than a larger tank that has a better chance of becoming – and remaining – stable.

What’s Considered a Small Fish Tank?

In my opinion, small fish tanks are anything under 20 gallons.

Anything under 5 gallons would be a nano tank, but for the purpose of this article, I won’t distinguish between the two.

With that in mind, when talking about small fish tanks, filtration becomes a major challenge and the smaller the tank, the more important filtration becomes. 

Which is why you need a small fish tank filter that can fit in a tank 10 gallons or less but still provides you with top quality filtration to ensure your tank remains healthy and clean.

A word of caution when purchasing a kit!

The filters provided typically are just enough filtration for the tank. As a general rule, I typically like to use a filter that is rated for a slightly larger tank than the tank I have.

Best Filter For 10 Gallon Tank

When selecting a filter for our 10 gallon I typically like to think of what I’ll be stocking this 10 gallon tank with?

For example, will it be heavily planted or heavily stocked?

All of this matters when selecting the right filter. A heavily planted tank won’t need much filtration as your plants will help filter the water.

However, a heavily stocked tank may require you to select a filter that is rated for a 2o or even a 30-gallon tank depending on what you keep.

I personally set up a 10-gallon tank with lots of plants, 6 glowlight tetra a few shrimp. For this tank, I used an Aquaclear 20 and the water always looks great.

In the end, just give some thought to what the aquarium will be used for.

Next, let’s look at 7 filters that would be great for a 10-gallon tank.

You can see that the only modification I’ve made to it is the pre-filter sponge that I’ve placed on the intake. This helps keep larger debris from getting into the filter allowing me to extend the time between cleanings, it also provides a great place for good bacteria to grow.

The Aqua Clear 20 will change the water in a 10-gallon tank 10 times every hour, which is ideal. So it would be a great 10-gallon fish tank filter and would keep the water crystal clear and well filtered.
