Physical & Biological Filtration: This replacement Bio-Sponge optimizes the colonization of anaerobic bacteria along with providing mechanical filtration that traps large particulate matter. 1-Pack: The package only contains a single Bio-Sponge. Although they are disposable they can be reused time and time again. Simply clean the Bio-Sponge in a separate container with some of your aquarium’s water.
