Details
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

How it compares
Fine-bubble diffusion at the pond bottom
The parts sitting at the bottom of your pond decide how well air turns into oxygen and circulation. Here is how a bare airline compares to this kit.
Bare airline
Open airline with no diffuser or valve
- Releases air in large bubbles that rise fast with limited oxygen transfer
- No check valve, so pond water can back up the airline when the compressor cycles off
- Weaker circulation from the pond bottom
This kit
Airstone diffuser and foot valve together

- Foot valve is a one-way check valve that stops water from backing up the airline

Fine-bubble oxygen transfer

Strong bottom-up circulation
