Improved design with other sponge filters: porous aquarium sponge filter-designed to reduce clogging and larger cleaning intervalsSize: about 12x14CM. Sponge filters provide a wide area where beneficial organisms can grow, which means they help keep the water in the aquarium exceptionally clean and healthy after they are established. Some studies have shown that sponge is actually one of the best materials used as a biological medium because it provides too much surface area for the growth of beneficial organisms. They also provide mechanical filtration to help keep the crystal clear.Simple: The sponge filter is the easiest aquarium filter to use and set up-The sponge filter is driven by air, which uses an air pump inserted into the sponge filter. When the air moves in the filter, it creates a small vacuum, sucking water through the sponge, just like the working principle of a siphon. This means that all the air bubbles in your aquarium can provide you with the additional advantages of filtration, while also providing some oxygenation to your water.Advantages: Sponge protects small fish and frying from being pulled into the filter. Biological filtration works normally even with power loss; the nitrogen cycle continues because the aquarium sponge filter retains beneficial organisms. Pump water from the lower part of the water tank to increase the water surface area and exchange carbon dioxide for gaseous carbon dioxide.Using the existing aquarium sponge filter will speed up the circulation of the new tank by adding beneficial organisms.Without air pump and optional air stone.Colour:blackMaterial:ABS+cottonPackage Contents:1 x Fish tank filterOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
