Active water: volcanic rock can increase the content of oxygen ions in the water, which can be added into the aquarium to effectively prevent and treat patients
Stable water quality: it can adjust the water that is too acidic or too alkaline to near neutral automatically.
Adsorption: volcanic stone has the characteristics of porous and large surface area, which can adsorb harmful bacteria in the water and have an impact on organisms. Placing volcanic stone in the aquarium can adsorb the residue and feces that can not be filtered out by the filter, so as to keep the water quality in the tank clean.
Cultivation of nitrifying bacteria: the high surface area produced by the porosity of volcanic rocks is a good hotbed for the cultivation of nitrifying bacteria in water, and its surface is positively charged, which is conducive to the fixation and growth of microorganisms, with strong hydrophilicity. It can greatly improve the water quality by converting NO2 and NH4, which are toxic to vertebrates, into No3, which is relatively less toxic.
Substrate material for the growth of aquatic plants: it can provide fertilizer for aquatic plants. In agricultural production, volcanic rock is used as soilless culture substrate, fertilizer and animal feed additive.
Plant planting: the volcanic stone is loose and porous, rich in minerals, disease and insect resistance, and low price. It is mostly used for soil preparation or pavement of succulent plants, with water absorption and moisture retention, heat preservation and air permeability, increasing soil permeability, preventing succulent plants from rotting roots and insect pests. Some plants that need to increase soil permeability can also add appropriate amount of small particles of volcanic rocks in the soil to prevent the adverse impact of soil water on plants.
