Micro bubble diffuser discs are an important component in establishing and maintaining a healthy hydroponic grow or outdoor pond environment. 5" diffuser disc produces high oxygen transfer micro bubbles to help keep plant roots oxygenated or pond fish healthy and ponds clear. Increases oxygen levels for healthy and happy plants and fish. Promotes growth of algae-controlling beneficial bacteria. Lowers levels of dissolved toxic gases and ammonia. Reduces sludge build-up on pond bottoms. Helps maintain an open-water hole in the ice during winter to release trapped toxic gases. Beats all air stones on the market hands down for $10. Aeration Pump sold separately (see 70 Liter/Minute pump for $22).
