If you are looking for a good canister filter for turtle tank that provides extremely noiseless operation for your tank that can hold up to 175 gallons of water, the AquaTop  CF Series Canister Filter is a great choice for you. It comes with a 9-Watt UV sterilizer, a feature that you won’t find in most of the other filters in this price range.

Thanks to this sterilizer, you can be sure that your tank will be free of all kinds of germs, parasites, bacteria, and algae. Therefore, the plants and fishes will get a comfortable environment to live in. Though this turtle tank filter is made from plastic parts, you can be sure of their quality.

However, for those who are new to these filters, it may take some time to install and start using this. The filter operates at a power of 525GPH (gallons per hour), which ensures that it makes the environment inside the tank safe and compatible with the fishes and plants.


  • Doesn’t make noise when in use
  • Comes with a 4 +1 Filtration System, due to which your tank is cleaned thoroughly of all debris, bacteria and algae spores
  • Very durable; works for many years without any issue

2.Marineland Multi-Stage Canister Filter for Aquariums
