EasyPro Rubber Membrane Air Diffuser 4" with barb

The Rubber Membrane Tubular Air Diffuser is an ideal addition to a pond aeration system to oxygenate and circulate the water in your pond or water garden. The increase in dissolved oxygen improves water clarity and quality, and the circulation makes water temperatures in the entire pond more uniform. These improvements help koi fish and other aquatic life. To operate, this diffuser must be connected with tubing to a compressor (air pump). Note: These rod-shaped rubber diffusers are very strong and easier to clean than air stones. Pump and tubing are not included. Each diffuser is 1.5 inches in diameter. Models with barbed inlets feature multiple sized barbs, which can be cut to fit a variety of airline tubing. Features benefits: These EPDM rubber air diffusers are incredibly strong and are ideal for pond aeration, circulation and de-stratifying applications. Unlike air stones these diffusers are easy to clean. In testing they produce a slightly larger air bubble than air stones which translates into less oxygen transfer into the water, so for fish holding tanks, raceways, fish production ponds, etc. we recommend air stones. Barbed inlets have multiple size barbs, simply cut to fit the size tubing you are using. An excellent choice for pond and water garden aeration since they actually produce more circulation and water movement.
