Blue Ball Air Stone
Hailea – Ring Diffuser Air Stone
Round Airstone
Our biggest air stones. These flat disc shaped air stones have a much larger surface area than the Golf Ball Air Stones, giving you more bubbles and therefore more oxygen into your nutrient solution. Simply attach to an air pump with air line (sold separately).
We recommend approximately one of these air stones per 50-100 litres of water to ensure ample oxygen infusion.
