How To Choose The Best Canister Filter For Turtle Tank?
Power
In general, remember that the more power, the better. Though the power required for each tank may differ in different cases, turtles tend to be of big sizes and they always cycle their waste into water.
In addition, there are other things in the tank such as small fish and plants. So you will likely have a large tank of 50 gallons or more. The water inside can get stagnant if not moved around, which will lower the water quality.
Circulating water is useful in distributing oxygen as well as good bacteria evenly around the tank, maintain a regular temperature, prevent harmful bacteria from growing, and reduce the growth of algae.
It’s worth noting that if there are water-dwelling creatures in the tank, you may consider getting a less powerful filter to save some money. But we still recommend choosing more power.
All in all, you should never opt for a weak filter as it won’t be able to handle the amount of water inside your tank or provide key benefits for your turtles. Remember to choose a powerful filter at all times.
Filtering stages
The rule when considering this factor is simple: the more stages the better, including a mechanical filtration medium like a net, mesh, or sponge.
The medium is responsible for accumulating physical debris like uneaten food, turtle waste along other types of waste.
There is ammonia in turtle poop that will be broken down, generating nitrite, which is toxic to your pets. However, a biological medium can further break it down into less harmful nitrate though it still needs cleaning.
If you want a crisp, clean tank, you should buy a chemical filter medium like activated coal or peat to deal with ammonia in the water. Don’t hesitate to invest in higher-quality and more stages, it’s either upfront or long-term cost anyway.
Warranty
While many may forget to look into this factor, warranty is another important thing that you must get. A warranty means you can have the filter replaced if you need to. However, remember to check the warranty policy and ensure it covers the entire filter.
Others
Apart from these major factors, there are other things that will help improve the life quality for your turtles, including a UV filter and a spray bar.
A UV filter helps limit algae from growing and purify the water. Meanwhile, a spray bar helps aerate the water inside the tank to make sure your pets have enough oxygen and are not affected by harmful bacteria.
