How the 8" (200mm) Flat Circular Airstone Works

The 8" (200mm) Flat Circular Airstone 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 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 airstone bottom and sides are protected by a plastic case and the bottom of the airstone has rubber feet to reduce vibration of the tank it is sitting in. This Airstone requires larger diameter airline than other aquarium-type airstones and will also require an airpump 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 airstone 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 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.

Using the 8" (200mm) Flat Circular Airstone

Connect the airstone to your air pump using non-standard 8mm pvc or rubber air line. If the air line is difficult to fit over the inlet, dipping the end in warm water should make job much easier. Always make sure that your air pump is at a higher level than the surface of the water in your reservoir to prevent water siphoning back into the air pump. Place the airstone at the bottom of your reservoir, making sure that the stone side is facing upwards and then switch your air pump on. The porous stone used in airstones is brittle and should be handled carefully to prevent breakages. Every so often, gently clean the surface of the airstone to maintain the air-flow and bubble production. Airstones do degrade with use and will become clogged and more brittle over time. Try to make sure you replace them regularly.
