Aqua One 105s Sponge - EcoStyle 42/47 - two pack

The Aqua One 105s Sponge pad set is a rinsable filter foam pack for use in the EcoStyle 42 and 47 aquariums . A pack of two is supplied and the sponge sheet should be removed and rinsed in a little aquarium water ( not tap water) when blocked with fish waste and debris. This will usually be every four to six weeks. After several months the foam cell structure begins to break down and the sheet should be replaced.
