Review on Enhance Aquatic Filtration with Powkoo Sponge Filter - The Ideal Corner Filter for Aquariums by Brandon Roman

Revainrating 5 out of 5

Every aquarium should have one.

I keep a filter in each tank as a secondary filter in case I need to use the hospital tank. I just need to put a sponge filter in the hospital tank to make it work. My betta first thought it was a scary bubble generator until I found it soft and perfect for sleeping. The angled shape, which is now one of its favorite things, also helps it not take up as much space in the aquarium.

Pros
  • Excellent overall performance
Cons
  • Requires an outlet
