Best Filters for Turtle Tanks – FAQs

Does a turtle tank filter always need to be on?

Turtles produce a lot of waste which is why you need a good enough filter to be able to cope. If you turn them off at certain times then the bacteria on the biological filtration will start to die and your filter will have to work even harder when you switch it back on. Turtles can be quite resilient to the likes of ammonia or nitrite but you still don’t want to expose them to spikes. It’s best to keep your filter on at all times.

Does turtle tank need filter?

In a word, yes. Without a filter, the water will quickly fill up with dangerous chemicals such as ammonia and nitrite while gradually losing oxygen. The only alternative to a filter is regular water changes but this is far from ideal, not as healthy and time intensive.

Can I turn my turtle tank filter off at night?

It can be tempting to turn it off, especially if you don’t like the noise but you should keep your filter on at all times.

How to clean turtle tank filter?

This will depend on the type of filter but it should be fairly simple. With biological filters you want to clean and unclog these but it’s best to use water from the tank to do this to not upset the balance and cause a shock to the environment. Chemical filters generally are replaced and not cleaned as they’ll become less effective over time. Your mechanical filter will need to be emptied regularly, depending on how messy your turtles are but this is often around once per week.

What is the best turtle tank filter?

We wouldn’t say there is one ‘best’ filter as everyone is different. All these filters we’ve looked at here are great and you want the one that closely matches your needs.

Why is my turtle tank filter so loud?

The main sources of noise come from the water being fed back into the tank and the motor. If your filter is louder than normal then give it a clean and check that the intake hose isn’t clogged. If that doesn’t solve the issue then it may have a loose or broken part.

Why is my turtle tank filter not working?

Filters can break down and sometimes they need replacing. Before that, you want to make a few checks. Ensure that there’s nothing clogging the system and give it a good clean. Also, check that it’s powerful enough for the size of your tank. If it’s still not working, then it will often be cheaper to replace your filter rather than get it repaired.

Final thoughts

Everyone is going to have different needs and the best filter for turtle tank for you may be different for someone else. Before you buy, it’s important to work out how big your tank is and where the filter is going to be placed.

All the models we’ve looked at here are fantastic and will do a great job of cleaning your turtle tank. The end result will be a healthy tank which will mean a healthy turtle. All you need to do no is pick your favorite filter and pop it into place.
