1. Large surface area, can attach a large number of nitrifying bacteria

Biosphere is a kind of hollow sphere made of plastic and biochemical cotton. It has a large surface area and can attach a large number of nitrifying bacteria. The hollow structure can turn the water into a small flow and break up large pieces of dirt, so the filtering effect is good. Because of its light weight and easy to carry, it can be used not only in seawater biochemical filtration system, but also in fresh water biochemical filtration system.

2. Porous structure, with filter inside biochemical cotton

Bio ball is a kind of bio filter with mesh structure. It has multi sheet structure and porous inside. It also provides a huge biochemical surface area for the growth and reproduction of nitrifying bacteria. The internal bio cotton cube accelerates the maturation of bacteria and further improves the biochemical ability of bio ball. It can be used in seawater and fresh water.

3. Detoxification, enhance oxygen solubility

Promote the metabolism of fish and discharge harmful substances, effectively increase the dissolved oxygen in water, remove harmful metal elements in water, purify water quality, promote the physiological metabolism of fish, and grow strong. In order to maintain the ecological balance in the aquarium, we should increase the conversion rate of food, reduce the input and increase the output.
