The Hailea Flat Circular Airstone is a ”slab” of porous stone. An inlet nodule is located on the inside of the ring to connect the airstone to an air pump via a length of air line. When connected to an air pump, the air will exit the airstone through the many pores in the stone. When the airstone 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 dissolved. Dissolved oxygen discourages anaerobic microbes, which can cause root diseases and feeds oxygen to the friendly aerobic microbes. An airstone helps keep your plant’s roots healthy while providing oxygen for the roots to absorb. The Hailea 4-inch airstone will sit flat at the bottom of a tank or reservoir. Adding an airstone to your reservoir really does increase the speed of your plant’s growth and creates a healthier root system. An airstone is very highly recommended for all hydroponic systems.
