Airstones circulate water which generates oxygen which is vital for fish tanks and hydroponics nutrient tanks / reservoirs. Air stones are also referred to bubblers and their micro-pore design energizes your growing solution as it aerates and circulates your nutrients. It helps with plant growth by extending your nutrient solution life's cycle and keeps your roots healthy by providing them with plenty of oxygen. 

To use an airstone is simple, just place the airstone within the water and connect it with tubing to a air pump.
