How the Air Stone Cylinder 3 Inch Works

The 3 Inch cylinder air stone is a 3 inch length of porous stone. An inlet nodule is located on the end to allow the air stone to be connected to an air pump via a length of air line. When connected to an air pump, the air will exit the air stone through the many pores in the stone. When the air stone is submerged in water or a nutrient solution, the effect is that many small bubbles are produced and released from the surface of the stone. The bubbles create movement in the water or nutrient solution keeping it well mixed. The movement at the surface also greatly increases the amount of oxygen being dissolved into it. Dissolved oxygen discourages anaerobic microbes which can cause root diseases and feeds oxygen to the friendly aerobic microbes. An air stone helps to keep your plant’s roots healthy while also providing oxygen for the roots to absorb. Adding an air stone to your reservoir really does increase the speed of your plant’s growth and creates a healthier root-system. An air stone is very highly recommended for all hydroponic systems.
