Frequently asked questions
What is the Golf Ball Airstone 50mm for?
It increases oxygen and airflow in hydroponic, reservoir and bubbler systems to boost nutrient uptake. It suits tanks up to 30 litres, is ideal for IWS systems and is recommended for Deep Water Culture.
How much airflow should I run through the 50mm Golf Ball Airstone?
Run up to 5 litres per minute through each stone. If you need a greater airflow rate, a ceramic disc may be a better choice.
What else do I need to use the Golf Ball Airstone?
It has a 6mm intake fitting and needs one piece of airline per stone, connected to an air pump. Running several stones from one pump needs a manifold. The stone can be suspended or left on the tank bottom.
