The "secret" ingredient to a clean-and-clear pond? The big "O"! The 7" Diffuser Airstone with Backflow Valve turns air into thousands of tiny bubbles so that oxygen can dissolve into the water and improve its health. Diffusing air into water can increases its effectiveness by over 1,000%! Includes a foot valve that prevents water from coming back up into the aeration tubing. FYI: Shallow or larger ponds may require multiple Airstone Diffusers. Dimensions 2 1/4 x 7". 3 1/2 lbs.
