LT20003 Bio Filter Media-Biofilter for Aquarium

The Bio Filter Rings are calcinated and formed under high temperature in annular shape with more coarse pores. It’s easier to create turbulence when water passes through it to smash large particulates. The material is natural clay, which is rich in minerals, including aluminum, magnesium, iron, sodium, kalium and calcium. This material is with electronegative, thus makes this bio filter media more absorptive. The Bio Filter Rings can be able to stop PH decreasing by releasing calcium and sodium slowly when the water PH is tending to be acid, thus to keep a healthy environment for the aquarium life.
