Product Description
The AQUANEAT Sponge Filter is a reliable and efficient filtration system for small aquariums. It provides both mechanical and bio filtration, making it an ideal solution for keeping your tank water clean and clear. The air infusion chamber produces minute bubbles, which increase the oxygen solubility of the water, creating a healthy environment for your fish.
How it Works
The sponge filter uses bubbles of air from an external air pump to draw water through the sponge, effectively removing debris and waste products from the tank. The sponge material is soft and gentle, trapping floating debris without sucking up your fish.
