The sponge filter consists of a 5.5" long cubelifter and a 3" x 3" x 3" Poret foam sponge (30 ppi) that is glued with silicone onto an unglazed porcelain tile. This filter is optimal for 2.5–5 gallon tanks. Over the years, we have 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 does not fall apart like other products. The Poret foam is specifically manufactured for aquarium and pond use and has a much larger inner surface than other filter materials (about 1800 sq. in. per quart of volume), which permits more rapid and superior growth of bacterial cultures.
