8" (200mm) Flat Circular Air Stone for High Output Air Pumps

8" (200mm) Flat Circular Air Stone

Keep your nutrient solution fully oxygenated with an air stone. This circular 8" version is great for the bottom of large reservoirs. PLEASE NOTE: This air stone requires non-standard 8mm wide airline and an airpump with a high output.

How the Flat Circular Air Stone Works

The 8" (200mm) Flat Circular Air stone is an 8 inch diameter "slab" of porous stone. An inlet nodule is located on the inside of the ring to allow the airstone to be connected 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 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 air stone bottom and sides are protected by a plastic case and the bottom of the air stone has rubber feet to reduce vibration of the tank it is sitting in. This Air stone requires larger diameter airline than other aquarium-type airstones and will also require an air pump with quite a high output to take advantage of it's size.

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. The Hailea 8 inch airstone will sit flat at the bottom of a tank or reservoir. 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.
