volcanic rock

1. Finely screen out high-quality volcanic rocks. 2. Fine screening to remove powder, fine size specification. 3. Simple grinding reduces the damage of edges and corners to plants.

1. The pores inside the volcanic rock are densely distributed, and the pores are the prerequisite for parasitic nitrifying bacteria. The ultra-microporous filtration is smooth and the oxygen content is increased. 2. The specific surface area of volcanic rock is large, which is conducive to the growth and reproduction of microorganisms on its surface and the formation of biofilm. Maintain a high microbial load. 3. The manufacturer sells volcanic stone directly, with good quality and favorable price, and there are two kinds of packaging, bagged and bulk.

1. The densely distributed pores of volcanic rocks are the prerequisite for parasitic nitrifying bacteria, and the special honeycomb network structure makes the filtration and permeation smoother. 2. Natural red volcanic rock, without pigments and additives, the color is pure and natural. 3. Red volcanic rock has high strength, acid and alkali resistance, corrosion resistance and no pollution.

1. Volcanic stone is used as the bottom of the fish tank to run water, absorb bacteria, promote metabolism, and stabilize water quality. 2. The volcanic stone that has been simply polished has no sharp edges and corners, which will not cause damage to the fish. 3. The bright color of volcanic stone has a very good color-attracting effect on some high-quality ornamental fish.

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.

1. Aquarium deodorant volcanic stone is selected from high-quality volcanic raw stone. 2. The volcanic stone is simply polished to reduce the edges and corners, and will not cause harm to fish. 3. Volcanic rock can purify water quality, promote fish metabolism, and facilitate the planting of aquatic plants in fish tanks.

1. Volcanic rocks are used for the cultivation and planting of potted flowers and plants, to enhance ventilation and speed up water seepage, and prevent root rot due to lack of oxygen. 2. The volcanic stone covering the surface around the flowerpot and green plants can have a high ornamental value. 3. Volcanic stone can be used for planting mixed soil and used together with other planting substrates.

1. Volcanic rock is formed by volcanic eruptions for hundreds of millions of years, with high hardness and not easy to pulverize. It can be washed and used repeatedly. 2. Volcanic rock has a large specific surface area and many pores, which is conducive to the reproduction of nitrifying bacteria and purifies water quality. 3. The pores of volcanic rock are dense and uniform, and the porous structure has strong adsorption capacity, which can effectively absorb harmful substances and improve water quality.

1. Fine screening selects high-quality volcanic rocks. 2. Fine screening to remove powder, fine size specifications. 3. Simple polishing reduces the damage of edges and corners to plants. 4.The volcanic stone has dense and rich voids, is loose, breathable and drains well, and is clean and free of germs. 5. Selected natural Changbaishan volcanic stone is not easy to pulverize and can be used repeatedly. 6. Volcanic stone is used for landscaping and laying, which can beautify the environment, cover the soil surface, reduce the planting rate and reduce manual maintenance.
