red lava

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. 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. Volcanic stone has good water retention, no secondary pollution, and good air permeability can provide trace elements. 2. The volcanic stone is mini porous, which can prevent soil from compacting, prevent root rot, loose and breathable. 3. Volcanic stone can be used as plant pavement, planting soil, flower pot bottom, aquarium bottom landscaping, garden landscape scenery and other multi-purpose use.

1. The volcanic rock has been sieved many times, and the particles are uniform. 2. Select the high-quality volcanic rock in the center of the volcanic eruption, with dense voids and rich trace elements and minerals. 3. Volcanic rock can improve the soil, cover the loess, and promote the growth of plant roots.

1. Volcanic rock material is weather-resistant, weather-resistant and durable; 2. Volcanic rock can absorb sound and reduce noise, which is beneficial to improve the auditory environment; simple and natural to avoid glare, which is beneficial to improve the visual environment; water absorption, anti-skid and heat resistance are beneficial to improve the somatosensory environment. 3. The unique "breathing" function of volcanic rock can adjust the air humidity and improve the ecological environment.

1. The volcanic rock is selected from high-quality raw mineral stones, with many voids, uniform particles, bright colors, and is water-permeable and breathable. 2. Volcanic rock can purify water quality and adjust the pH value of water. 3. Volcanic rock can absorb harmful bacteria in water and promote fish metabolism.

1. Volcanic rock is used to cover the surface of flower pots, which can reduce water volatilization, prevent soil from splashing when watering, and can also retain water and fertilizer, and absorb harmful substances. 2. Volcanic rock is used as a bedding at the bottom of the flower pot, which can enhance the aeration of the substrate and speed up water seepage. 3. Volcanic rock and peat, leaf humus, coconut peat and other planting media can be mixed as planting nutrient soil.
