Scott Bubble Pro Max Bottom Diffused Aeration System Elevate the health and clarity of your pond with the Scott Bubble Pro Max Sub-Surface Aeration System. By discreetly introducing oxygen from the bottom up, this system delivers enhanced water quality and a more vibrant aquatic environment—without disrupting your pond’s natural look. How It Works Sub-Surface Diffusers Three diffuser modules rest on the pond floor, connected by weighted tubing. An onshore air compressor pumps oxygen-rich air through the tubing to the diffusers. Oxygenation Process The diffusers produce thousands of small air bubbles that rise to the surface, creating an upward current. Water at the bottom is lifted to the top, where it becomes oxygenated as it contacts the atmosphere. Healthy Circulation The constant water movement helps maintain stable oxygen levels, supports beneficial bacteria, and promotes a cleaner, clearer pond.
