The sponge filter consists of a cubelifter and a 5" x 5" x 7" Poret foam sponge (25ppi) that is glued with silicone onto an unglazed porcelain tile. This filter is optimal for 30-50 gallon tanks. Over the years, we tested several sponges in our hatchery and believe that this sponge (made by Swiss Tropicals) is one of the best on the market, simply because it does not clog quickly and it does not fall apart like other sponges. The Poret foam that the sponge filter is made of is specifically manufactured for aquarium and pond use and has a much larger inner surface than other filter materials (about 1800 sq. inches per quart of volume), which permits more rapid and superior growth of bacterial cultures.
