Hailea Golf Ball Air Stones are used to aerate aquariums and hydroponic grow systems. By allowing more the plant's root system becomes much stronger.
An inlet connection is located on one side to allow airline tubing to be connected to an airstone.
Once the Hailea Golf Ball Air Stone is connected to an air pump, air will bubble out of the porous stone.
Submerge the air stone so the tiny bubbles will mix with the nutrient solution oxygenating it.
