Filter Air Replacement Sponges

The Aqua One Filter Air Replacement Sponges are specifically designed to fit the the Aqua One Filter Air Sponge Air Filters. Supplied in 3 sizes to fit each of the 4 models, the sponges should be replaced periodically, only changing one sponge at a time for the dual sponge models.

The custom-made sponges provide effective mechanical filtration, trapping debris and dirt particles from within the aquarium. They are also an ideal home for beneficial bacteria which help breakdown harmful fish waste and other toxins. This mix of both mechanical and biological filtration is an ideal combination to create perfect healthy water conditions for your aquarium inhabitants.
