Mineral and Safe Material The air stones for ponds are made of high temperature sintered high-density mineral materials. They are strong, breathable and durable. They will safely and reliably generate a large number of dense bubbles to increase the solubility of oxygen in the aquarium. EVEN BUBBLES The pores of the aquarium air stone are even and thin, which will produce dense bubbles when the air pump is working, such as atomization effect, with high dissolved oxygen content, which will not affect the healthy growth of fish/organisms or roots. EASY TO CONNECT Stainless steel angled interface, sturdy, corrosion resistant, rust resistant, convenient 90 degree connection angle. The chassis is perfectly integrated, and the interface ring is made of epoxy resin, which has good water resistance and is more durable. Increase Oxygen Aquarium air stones increase oxygen in tanks and air circulation by creating tiny bubbles that improve the efficiency of water filters. Beneficial to the health of aquatic life and plants while adding beauty to your aquarium. MULTI-SCENE APPLICATION Our aquarium air stones are a good way to add oxygen to aquariums, small ponds, hydroponics, small gardens or circulation systems. Note: Soak the air stones completely in water for 1-2 hours before use. Clean regularly with a brush.
