Petworx Large Bio Sponge Filter for Aquariums
The Petworx Large Bio Sponge Filter is a simple, reliable, and highly effective aquarium filtration system designed to keep your aquatic environment healthy, stable, and crystal clear. Perfect for freshwater aquariums, axolotl tanks, shrimp tanks, breeding tanks, fry tanks, and quarantine setups, this sponge filter provides excellent biological and mechanical filtration with gentle water flow.
Powered by an aquarium air pump, the porous sponge draws water through the filter as air bubbles rise through the uplift tube. During this process, the sponge traps waste and debris while also providing a massive surface area for beneficial bacteria to grow.
These beneficial bacteria help support the aquarium nitrogen cycle by converting harmful ammonia and nitrite into less harmful nitrate, helping create a safer and healthier environment for fish, axolotls, shrimp, and other aquatic life.
