Airstones/ Air Diffusers are a critical component of all pond aeration. Whether the goal is to aerate a koi pond, water garden, earth bottom pond, an area of a lake, or a water hazard on a golf course, the air must be correctly transferred from the airline to the water column. Bubbles that are too large do not properly deliver oxygen to the water column. Conversely, air bubbles that are too small do not circulate water properly making the oxygenation process pointless. These airstones are properly designed to adequately deliver oxygen and circulation.
