These airstones are bigger than the ones we usually use on our systems, I personally prefer these big ones for the heavy duty commercial metal air pumps but they will work on any airpump.- Gary


Active Aqua air stones are an ideal way to add oxygen to your hydroponic growing system. The micropore design energizes the growing solution as it aerates and circulates nutrients. Air stones will extend the life of your nutrient solution, help keep roots healthy, and promote exceptional growth.

Choose from three versatile cylinder sizes. This one is 4" long by 2" in diameter, our largest cylindrical air stone available. Fitting accepts 1/4" air tubing.
