Volcanic Rock Biological Filter Material
1. The natural honeycomb of volcanic stone is porous, has the environment for the growth of nitrifying bacteria, and is not easy to be blocked. It distributes water and air evenly, which is conducive to the growth of microorganisms. It has strong hydrophilicity, and the amount of attached biofilm is large and fast. 2. Volcanic rock can absorb harmful heavy metal ions and harmful bacteria, and play the role of purification and filtration. 3. Volcanic rock has good chemical stability, neutral pH, not hard water, and does not increase the pH of water.
