Sunsun 500g Hollow Quartz Balls Media Aquarium Fish Tank Pond Filter

Product Description: 

The hollow quartz spheres are made by mixing high-quality quartz, kaolin, and other materials, then sintered at high temperatures. 

The hollow structure of this product accelerates the reproduction of anaerobic bacteria. The numerous micropores can adsorb harmful substances in the water and fine residues that the filtration system cannot filter, helping to maintain long-lasting cleanliness in the tank. It also helps stabilize the pH value and activates the water quality, protecting the balance of the aquarium ecosystem. This promotes the growth of ornamental fish and improves their survival rate.
