Air inlet: 304 stainless steel and chrome-nickel stainless steel, high strength, good corrosion resistance, heat resistance, low temperature resistance and mechanical properties; good hot workability, such as stamping and bending, without heat treatment hardening situation.2. Sturdy and durable: lgneous corundum material, high temperature resistance, corrosion resistance, high strength, vitreous luster, hardness 9. Specific gravity 3.954.10. The bubble stone will not break or drop dust after long time use.3. High dissolved oxygen: The air bubbles made by the corundum material are getting finer and finer. The area in contact with the water surface is larger, which effectively increases the amount of dissolved oxygen and makes the fish more cheerful.4. High-density holes: The fish tank bubbler adopts high-density holes, the bubbles are finer, the air outlet is uniform, and the atomization effect is not easy to block. Avoid noise and ultra-high dissolved oxygen, it is better to clean once every 2 months.5. Ultra-thin ceramic heavy body: Aquarium bubble stone prevents displacement caused by water flow, has weight, prevents the air plate from being displaced by the water flow and hits the landscape in the fish tank, affecting the visual experience.Specification:Item Type: Air Stone Disc for AquariumsMaterial: CeramicHow to Use:Preliminary Preparation:. Soak it in water for -2 hours. Fill the air stone with water for the best effect. Please refer to the instructions on the back for the water filling method.2. No matter where the air pump is installed, a check valve must be installed, otherwise the air stone pressure
