Review on 🐠 Enhance Water Filtration with Powkoo 4-Layer Corner Sponge Filter for Aquariums by Kelly Miller

I bought this for my Betta aquarium. I also bought a Mylivell silent air pump. This filter floats. I used the double ended suction cup that came with the air pump. and it stays good. The device appears to be working properly. I put this filter right in the corner. My rooster played with bubbles and ran around the pump all day. It got stuck at the bottom of the filter. It doesn't really suck up fish like a cartridge filter so I thought it was safe but since the rooster fish loves to explore new things it got stuck and struggled to come back to get out. I couldn't move the filter when it got stuck underneath because I then had to move the suction cup and this could harm my fish. He got out alone, but one of his pectoral fins was paralyzed. It moved in a few minutes and was completely back within a day. I moved the filter, leaving about an inch from the corner for my fish to swim. Since then my fish have never had any problems.
