I have a 2-3 inch musk turtle in it. He creates a LOT of waste. My RES was never so dirty. ;_; I know this forum is for RES, but it's still an aquatic turtle. Just a messy one. He has a turtle pier as a basking platform (even though he doesn't use it) and a Regent filter that is meant for a 29 gallon aquarium. It just isn't keeping the water clean at all though. The water is half way up since he's not that strong of a swimmer yet.
So any suggestions on what filter would be good for that size tank, turtle, and water level?
