Description
The Aqua One 95s Sponge pad is a coarse rinsable filter foam block for use in the Aqua Nano 25 aquarium. The foam block traps larger debris and cultures helpful aerobic filtration bacteria. The sponge block 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 block should be replaced.
