Bio Sponge Filter Breeding Fry Betta Shrimp Nano Fish Tank Aquarium

Description

Features:
More Bubbles for Your Fish: Our sponge filter is good for aquariums and provides both mechanical and biological filtration. The air infusion chamber produces numerous minute bubbles which promote gas exchange and increase dissolved oxygen levels in tank water.
Easy to Use: Just connect the unit with an air pump through airline tubing and it will provide both aeration and filtration for your tank.
Cleaner Water: The sponge can trap large waste particles to clean the water without trapping baby fish. They are useful as a breeding filter or as a secondary filter. Or they can be used as pre-filtration units by fitting to an external or a top filter.
Easy to Clean: About every 2 to 4 weeks, the sponge needs cleaning when becoming dirty. It's helpful to reserve the beneficial bacteria by washing the sponge gently with water from the fish tank instead of tap water.
