AIRSTONE AQUA 4.25″

The AQUA O2 4.25″ Round Air Stone is a high quality, new and innovative air stone that is sure to bring an entirely new dimension to reservoir aeration. This simple, yet uniquely designed air stone will remainstationary in your reservoir without the need for gravel or glue to hold it in place. Three attached suction cups allow the user to mount the air stone vertically or horizontally, creating the opportunity to add multiple air stones in a variety of positions to fully maximize the total dissolved oxygen levels within a nutrient solution. The AQUA O2 Air Stones are made from silicon carbide fired at 1300 Celsius, which creates much smaller bubbles than blue ore air stones fired at only 200 Celsius. AQUA O2 Air Stones ensure only the highest quality, most effective oxygen delivery within your nutrient solution possible.
