Petworx Medium Bio Sponge Filter
Keep your aquarium water clean, healthy, and biologically stable with the Petworx Medium Bio Sponge Filter. Designed to provide both mechanical and biological filtration, this reliable sponge filter is an excellent choice for axolotl tanks, freshwater aquariums, shrimp tanks, fry tanks, quarantine systems, and breeding setups.
Powered by an air pump, the Petworx Medium Bio Sponge Filter gently draws water through its high-quality sponge, trapping debris while providing an ideal surface for beneficial bacteria to colonise. These beneficial bacteria naturally break down harmful ammonia and nitrite as part of the aquarium nitrogen cycle, helping maintain safer water conditions for your aquatic pets.
Its gentle water flow makes it especially suitable for axolotls, shrimp, baby fish, and other delicate aquatic species that prefer low-current environments.
