Aquarium Bio Balls w/Sponge Filter Media Bag Wet/Dry Koi Fish Pond Reef 16-56mm

Description

Descriptions:
The bio-ball is a hollow sphere made of plastic material. Its large surface area can attach a large number of nitrifying bacteria. There is no resistance when the water flows through, and the hollow structure can divide the water into small streams and break up large pieces of dirt, which has an excellent filtration effect. Due to its light weight and easy portability, the bio-ball can be used not only in biochemical filtration systems in seawater, but also in biochemical filtration systems in freshwater.
The principle of the biochemical ball is to let the water flow through the tortuous space distributed inside to prolong the time of the water flow, and add the nitrifying bacteria attached to the scattered multi-column structure inside to achieve the effect of biochemical filtration. The filter of each aquarium is limited, and the filtering space for placing the biochemical ball is not too large, but it is the function of the biochemical ball to make up for the lack of filtering space.
