Rena XP3 Filter Review [Discontinued]

Filstar Rena XP3 Review

The Rena XP3 Filter is no longer for sale, but was highly recommended and inexpensive option to add into your turtles enclosure while still ensuring it operated at the highest possible level.

A great alternative to this canister filter is the Fluval Fx4, which is rated for up to 250GPH.

You can read more about it on our page about choosing a filter for your turtle tank. There are other options listed there as well as all the things to consider when purchasing a filter.

A filter is a vital part that helps your animals receive oxygen and also cleans the water with regular circulation.

It’s important to ensure that ammonia and nitrite are removed from the tank which is done through a filter.

When looking for a suitable filter you need to ensure that it is durable and easy to clean, as well as is a reliable product to add into your enclosure.

What are you looking for when choosing a filter?

When choosing a filter, a reliable product that has been tried and tested is key. The best options will have a three stage filtration system – one that is mechanical, chemical and bacterial.

A mechanical filtration system catches waste, or any other floating particle in the tank and a chemical filter will ensure that the decomposing waste does not change the chemical balances.

A bacteria filter boosts beneficial bacteria in sponges, bio-cubes or within the filters.

Something to also keep in mind with your filter, when you clean it you should not automatically remove the water and clean the sponges under tap water as healthy bacteria will have built up in there.

By removing healthy bacteria and placing new water into the filter you risk harming your turtles.

The product should be made of high quality material, and should be sized correctly for your tank and its needs. For example, for small species of turtles such as Mud turtles that get up to 5 inches big, you will need a 50 gallon tank (the size of your turtle multiplied by 10 for one turtle).

The filter will therefore need to be able to filter 25-50 gallons of water for small turtles and over 150 gallons for larger turtles or multiple turtles kept together in a larger tank.

Additionally, if the product comes with a warranty and is easy to install and maintain then it is especially worth investing in. Another bonus to look for in a filter is if it works quietly.

You should also bear in mind that your turtle enclosure will need a strong and reliable filter as turtles create more waste than fish. It is advisable to choose a filter than can work for a tank 2-3 sizes larger than your current one due to this.
