Review: Fabulous and already assembled! - These come preassembled and do a great job of keeping a 100 gallon stock tank for an 8 year old peninsula cooter. Turtles are notoriously dirty and it’s not easy to keep his tank clean. Rinse well prior to use! I have 2 filters and I change one of the filters weekly, alternating and rinsing the one I don’t change, very well. These filters make it so much easier to keep his tank crystal clear!!
