3 Filter sewage, improve water quality and reduce fish mortality.
4 Dense pore clearance and softness material allow to cultivate the best nitrifying bacteria.
5 Excellent material will never be deformed for long service life and can be any shape cutting for filter space. It's the best biological filtration media and usually replace onec in two months when the phosphate and ammonia concentration, it is recommended to shorten the replacement time .

◆ White (anti-algae-cotton): Bio-organic filter fiber cotton, which can absorb phosphate (PO4) in tank or pond to remove organic wastes and pollutants. Prevent algae from breeding and have remarkable effect.
◆ Blue (biochemical cotton): dense density of blue biological cotton, the most suitable for the cultivation of nitrifying bacteria and extend the service life.
◆ Black (bamboo carbon cotton): can effectively absorb harmful heavy metals and harmful substances or eliminate odor as well as water absorption residual chlorine, organic acids and ozone.
