Boyu 50mm Airstone Ball
About this product
The 50mm ball airstone is a 50mm diameter ball of porous stone. An inlet nodule is located on it 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 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. 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.
Connect the airstone to your air pump using 4mm 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. Lower the airstone down to the bottom of your reservoir and 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.
