Air compressor and diffusers allow big volumes of low pressure air to be moved to the lake bottom, converted to tiny bubbles which race to the top. Not only does this add air to deep water, it creates a current. Moving air rapidly through water creates an upward movement of water, mixing deep water throughout the water column where the aeration system is placed. Aeration and moving water are good.
