The Airstone Diffuser and Foot Valve Kit pairs the two parts that do the work at the bottom of your pond. The airstone diffuser breaks compressed air into a column of fine bubbles for efficient oxygen transfer and strong circulation, while the foot valve is a one-way check valve that stops pond water from backing up the airline when the compressor cycles off.
What is included
- One airstone diffuser for fine-bubble aeration and circulation
- One foot valve to prevent water backflow into the airline
- Available in 3/8 inch and 1/2 inch to match your airline
