Biochemical Sponge Filter provides both mechanical and biological filtration. Biochemical Sponge Filter provides both mechanical and biological filtration.
HOW IT WORKS: The air pump pushes air through the tubing into the hollow cavity inside the sponge filter. Bubbles rise from the inside of the sponge, thus drawing water through the sponge walls. This water suction process mechanically collects debris from the aquarium and gives beneficial bacteria place to grow.
INSTANT CYCLED TANK: You can never have too many! We always have a spare CYCLED Sponge filter running in one of the tanks, for last minute tank setups or quarantine/hospital tanks. You never know when you need an instant cycled tank .
Sponge filters are excellent due to their gentle flow. This allows for set-ups for fry, betta and shrimp tanks that thrive in low-flow (depending on air pump strength) filtration
