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

I love having a sponge filter for extra filtration and airflow and this one was perfect for my tank. It fits in a corner and is easy to hide from my plants and provides excellent airflow and filtration. The only reason I'm giving it 4/5 stars is that while it seems heavy, it wanted to float a lot so it took me some maneuvering to get it stuck in my substrate without trying to move. It would probably be ideal in a sand tank that could go around the base a lot more to weigh it down. Freddy Krueger (Shrimp) is also happy about that. The Kuhli's pasta gang (spaghetti, rigatoni and ravioli) were too busy hiding in their favorite spots not to attend the photo shoot.
