Fish Keeper Pro –
While the Penn-Plax Premium Underground Aquarium Filter does a decent job for its size, I found it a bit underpowered for a heavily stocked 10-gallon tank. It works well for light bioloads, but you might need additional filtration if you have more fish. The build quality is good, but the flow rate could be improved.
