The PondHawk® Mooring™ Depth-Adjusting Diffuser (pat.) isn’t just another aeration component — it’s engineered efficiency for your pond. Designed with a buoy-anchor system that automatically adjusts to changing water levels, Mooring keeps diffusers at the optimal depth for maximum aeration while safeguarding equipment against sediment and flooding. It’s the problem solver for stormwater ponds. With year-round oxygen delivery and temperature destratification, Mooring ensures healthier water, reduced algae growth, and long-term water circulation with minimal maintenance. Historically, the water components of subsurface aeration systems had a reputation for being covered with sediment settling on the diffuser head during storm events, or becoming untethered and taken downstream during an extreme storm surge. With the PondHawk Mooring, we solved this problem by simultaneously anchoring the components in a surge while elevating the Guardian™ Platform and diffusers above settling sediment.
