The Airstone Diffuser is ideally suited to work in conjunction with our Windmill to diffuse the air at the bottom of the water source. Aeration is most effective when air bubbles are very small. Small bubbles increase diffusion of oxygen from the air into the water.
The Foot Valve is used in conjunction with Koenders Airstone Diffuser to prevent the back flow of water.
The kit includes Airstone Diffuser and one-way Foot Valve.
