Multifunctional：Increase the flow of water, increase oxygen, adsorption magazine, cultivation of nitrifying bacteria.The water in the fish tank will produce toxic ammonia and nitrite. Simple physical filtration cannot remove these toxic substances. To improve the water quality, a nitrifying bacteria system must be established for the fish tank.
Changeable Filter Sponge:Sponges can be cleaned and used repeatedly.High-density sponge, which can adsorb tiny garbage particles and clean and filter water. However, the most important function of the sponge is to prevent fish waste and other debris from entering the biochemical filtration chamber, which could affect the nitrifying bacteria system.
Warning：The water pump must not protrude more than 0.4 inches above the water surface; otherwise, it may be damaged due to overheating.
Biofilter balls: Cultivate nitrifying bacteria to improve water quality. Do not clean. The establishment of the nitrifying bacteria system usually takes 2 to 8 weeks.
