How it functions: Sponge filter is an efficient and excellent method of filtration for your fish tank. This sponge filter works with an external air pump or an integral water pump. The air pump pushes air into the hollow cavity inside the sponge filter thru the tubing, and bubbles rise from the toplift tube thus drawing water thru the sponge walls. It provides mechanical and bio filtration for your tank. Easy maintenance: Scoop some old tank water out of your tank into a bucket; wash the sponge in the water and squeeze out the buildup until it's clean. Sponge needs to be cleaned every month. It's recommended to change out 25-30% of the water weekly. The air infusion chamber produces numerous minute bubbles which promotes gas exchange process and increases dissolved oxygen level in water. Constructed with a fine sponge, each sponge filter is good to use for tank up to 15 gallon. It measures 3.5 inches wide and 5.5 inches high. The sponge filter is designed to attach to the tank glass by a suction cup. All parts can be detached for cleaning or replacement. When taking the sponge filter apart, you should wash and clean the sponge foam with tank water instead of tap water.
