Specification selection: Aquarium filtration: Prioritizes 3-6mm particles, taking into account both adsorption and water flow permeability. Gardening surface: It is recommended to use 5-8mm particles to avoid dust affecting plants. Industrial filter media: Select a particle size of 10-20mm or 20-30mm based on processing requirements to balance the biofilm formation amount and backwashing effect.
Quality identification: High-quality products should have uniform particles and no obvious dust. After soaking in water, the water quality should be clear and the pH value should be stable between 6.5 and 7.5. It is recommended to choose suppliers that have passed the CMA/CNAS certification to ensure that the content of heavy metals complies with national standards Pretreatment method: Newly purchased volcanic stones should be rinsed with clean water 2 to 3 times to remove surface dust and prevent clogging of filter materials or affecting soil aeration.
