AquaMaster's AquaAir provides ponds and lakes with superior aeration, circulation and de-stratification. Dissolved Oxygen (DO) levels are increased throughout the entire water column with the use of bottom-mounted diffusers. The micro-bubbles draw water from the pond floor to the surface where atmospheric oxygen is absorbed and then transferred throughout the water column. System sized range from 1/3 to 1 HP with one to six diffusers.
