How it works

The ultrasound produces a pattern of increasing and decreasing pressure on the surface of the net which causes a process called non-inertial cavitation. This causes microscopic bubbles to be created by the reduced pressure cycle implode as the pressure increases. The microscopic agitation has a cleansing effect which destroys surface algae. By disrupting this first link in the food chain, the surface is kept clean and makes it much less hospitable for larger organisms that feed on the algae. The microscopic movement of water also prevents barnacle and mussel larvae from embedding on the surface.
