Hailea Golf Ball Air Stone
£1.50
The Hailea Golf Ball Air Stone is a 2-inch diameter golf ball of porous stone, hence the name.
An inlet connection is located on one side to allow airline to be connected to an air stone.
Once connected to an air pump, air will bubble out of the porous stone. Submerge the air stone so the tiny bubbles will mix with nutrient solution oxygenating it.
