Aquarium Accessory Set, 80mm Aquarium Air Stone with Air Tube, Regulating Valve, Anti-Return Valve, Y Connection, Suction Cup for Aquarium, Pond, Hydroponic Systems

This kit includes 1 air diffuser, 1 control valve, 1 non-return valve, 2 suction cups, 1 Y-connector and 1.5 m air hose. Air pump not included. Compatible with different power devices. The regulating valve allows precise adjustment of the bubble flow, and the suction cup holds the diffuser firmly. The assembly is simple and intuitive; even beginners can quickly install the entire system. 2 inch air diffuser is suitable for small and medium size aquariums (5-30 gallons) with 1.5-2W air pump. For deeper aquariums, a more powerful air pump can be used for optimal aeration. The Y connector allows multiple air channels to be created, suitable for home aquariums and hydroponic systems. Made of high temperature sintered silicon carbide, this stone is covered with fine and uniform micropores. After aeration, it produces many medium-sized soft bubbles, greatly increasing the contact area between water and air and thus improving the oxygenation of the water. This material does not release any harmful substances. The air stone has a compact and sturdy structure, resistant to water pressure and durable. Reusable many times, it can reduce the cost of replacing aquarium supplies. It is suitable for aquariums of different sizes and various oxygenation needs. (Note: Prolonged use may clog micropores; regular brushing will restore air.) Before first use, soak the oxygen stones in clean water for 2 hours to completely moisten their internal micropores. This system ensures optimal oxygenation of fish and shrimp, improves water activity and generates numerous bubbles. Suitable for home aquariums, outdoor koi ponds and deep water hydroponic systems.
