Quartz is a mineral with stable physical and chemical properties. It has good acid resistance and stability, equivalent to 30 times that of acid resistant ceramics, and will not be corroded by other acidic substances. So it won't affect water quality changes and has strong hydrophilicity.
Quartz balls can eliminate toxic ammonia nitrogen and nitrite nitrogen. The spherical structure has a large water inlet area and a huge surface area for the growth of nitrifying bacteria. And quartz balls have high hardness, making them easy to clean and reuse.
Quartz spheres have a high density, and the anoxic zone in the gaps can effectively cultivate anaerobic bacteria. Anaerobic bacteria convert difficult to biodegrade organic matter into smaller organic matter that can be biodegraded, achieving the effect of water purification
