Airmax Complete ProAir Weighted Diffusers are designed to deliver consistent, efficient pond aeration with minimal setup and long-term reliability. The self-weighted diffuser plate assembly sinks naturally, eliminating the need for bricks, straps, or improvised weights. Each diffuser features two heavy-duty membrane diffuser sticks that create uniform bubble distribution for improved oxygen transfer. Unlike traditional air stones, the flexible membrane design resists clogging, cracking, and debris buildup, making these diffusers virtually maintenance-free. Why Choose Airmax Koi Air - Self-Weighted Diffuser? Self-Weighted Design: Built-in weight ensures the diffuser stays on the pond bottom without extra hardware. Efficient Oxygen Transfer: Dual membrane sticks produce fine, uniform bubbles for improved absorption. Wide Airflow Range: Handles airflow from 0.8 to 3 CFM for flexible system design. Low Maintenance: Membrane diffusers resist clogging and eliminate stone replacement. Quick Installation: Integrated 3/8" barbed inlet allows fast connection to standard airline. Compressor Protection: Included check valve prevents water from entering the airline when the pump stops. PRO TIP For best performance, match diffuser airflow rating to your compressor output. Oversupplying air can reduce bubble efficiency, while proper matching maximizes oxygen transfer and diffuser lifespan. Show more
