Biosphere is a kind of hollow sphere made of plastic and bio chemical cotton. It has a large surface area, which can attach nitrifying bacteria to propagate and grow well, slow down water flow, divide water flow into small streams, better filter impurities and cultivate nitrifying bacteria. Compared with ordinary filter materials, biosphere is more effective, simple and convenient to use, and does not need to spend more time and energy.

1. Porous structure

To provide a better environment for the growth of nitrifying bacteria

2. Concave convex design

It can play the role of uniform distribution of water flow in filtration, and can be used for all kinds of filtration.
