A sponge filter provides a vast area on which beneficial organisms can grow, this means that they help to keep your aquarium water extra clean and healthy once they are established. It has been noted in some studies that sponge is actually one of the best materials to use as bio-media, as it provides so much surface area for beneficial organisms to grow on. They also provide mechanical filtration which helps to keep your water crystal clear. EASY: Sponge Filters Are the Easiest Aquarium Filter To Use And Setup! - Sponge filters are powered by air, this works by using an air pump plugged into the sponge filter. As the air moves up through the filter it creates a small vacuum that pulls water through the sponge, much like how a syphon works. This means that all those bubbling air stones in your aquarium could be giving you the added benefit of being filters too and still provide some oxygenation to your water. BENEFITS: The sponge protects small fish and fry from being pulled into the filter The biological filtration works even with the loss of power; the nitrogen cycle continues as aquarium sponge filters keep good beneficial organisms Draws water from lower parts of the tank to increase water surface area and gas exchange of CO2 for O2 Using an existing aquarium sponge filter will speed up the cycling of a new tank by adding beneficial organisms.
