Review on PULACO Aquarium Internal Filter for 3-20 Gallon Tanks: Ideal for Turtle, Reptile, Amphibian, Frog, Cichlid, Newt, and Fish Tanks by Satish Simone

I was dying to use this for my turtle tank. I love it. It seemed to work better than any other filter I had and kept the water almost crystal clear. It perfectly cleans the water and does not make any noise. It has a beautiful waterfall effect. The only problem I've found is that the sponge filter fills up with dirt pretty quickly. Turtles are notoriously dirty and I have to clean the filter almost every day to keep the filter from clogging. I think it would be great for aquariums with fish like cockfighters or shrimp that need a softer filter. Maybe I'll try again later with my turtle, because she really liked the waterfall on this one better than on my old one.
