Review on 🐠 CNZ XY-2893: High-Performance 10 Layer Bio Sponge Filter for Breeding Fry Betta Shrimp Discus Angelfish Nano Fish Tank by Melissa Richards

My tank has been without a filter for a long time. The dirt that accumulated at the bottom of the tank was quite uncomfortable. In three days this thing made my aquarium crystal clear. I washed the sponge once, it "absorbed" a lot of dirt and then it works wonders. I chose this one because of the good features. The top outlet has a 90 degree angle that provides a directional flow of water that you can control. This allows you to create circulation in your aquarium. In addition, the longer hose of this filter offers more suction compared to other filters with a shorter filter.
