Product Details

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.

*"The size of the bubble that an air stone produces makes a significant difference in their ability to add dissolved oxygen to water. If a single large bubble and 8 small bubbles have the same total amount of air inside of them, then the surface area of the smaller bubbles will always be greater. Consider this example: a bubble with a 5 mm diameter has a volume of 524 mm3 and a surface area of 314 mm2. A bubble with a 10 mm diameter has a volume of 4,188 mm3 and a surface area of 1,256 mm2. The 10 mm bubble could be divided into eight 5 mm bubbles, which would have a combined surface area of 2,512 mm3. By producing bubbles that are half the size, the surface area is effectively doubled, doubling the surface contact of bubbles to water therefore doubling the capacity of the air to increase the DO level. Additionally, smaller bubbles are less buoyant and rise through the water slower, allowing them to diffuse more oxygen into the water. Smaller bubbles are produced by high quality gray air stones made from silicon carbide, which is fired at 1300 degrees Celsius. The high temperature produces a more porous stone which makes smaller bubbles than the less expensive blue air stones which are only fired at 200 degrees Celsius.*
