I own the Walmart 55 gallon kit. If you can buy a bare tank instead, do it. The filter in the kit is in my stash of spare parts and an old sponge filter that I had on hand is serving the tank. That filter was a total waste of perfectly good plastic that someone else might have made into a nice filter. The almost universal practice of making the impeller housing an integral part of the filter housing is even absent on that thing. I am afraid it would start leaking rather quickly if I decided to place it into service.
