Product Description

The Rubber Membrane Air Diffuser is an ideal addition to oxygenate and circulate the water in your pond or water garden. The increase in oxygen improves the water's clarity and quality, and the circulation makes the water temperatures more uniform. Both improvements help koi fish and other aquatic life. To work, this diffuser must be connected with tubing to a pump. (Pump and tubing are not included.) 

This EPDM rubber air diffuser is available in different lengths. Each diffuser is 1.5 inches in diameter. Models with barbed inlets feature multiple sized barbs, which can be cut to fit tubing.
