Air Tube Diffusers
Air tube diffusers are our #1 recommended air diffusers for Koi ponds and water gardens. These quality units offer superior performance compared to other diffusers on the market and connect to standard 5/8" tubing, which is the same tubing used by most air pumps. These quality units are also available in 12" and 24" sizes to suit your specific needs. One of the best values in the pond industry today.
