I have a 55 gallon tank filled about 3/4s with a Reeves and Cagles turtle. I’m currently using an Ovation 1000 submersible internal filter that has a 265 gph. It’s positioned on one side of the aquarium and not filtering the turtle waste on the other side of the tank. I’m wondering if I get a canister filter and position the intake on one side of the aquarium is it strong enough to filter out the waste on the other side of the aquarium. I do have a lot of decor that can get in the way also. Thanks for any replies.
