Energy Efficient
Highly efficient 100-watt system designed to deliver stronger ultrasonic algae control
EnviroSonic uses low-frequency ultrasound to control blue-green algae (cyanobacteria) without chemicals or harm to the natural environment.
Operating at frequencies between 15–50 kHz, our systems disrupt algae at a microscopic level using controlled ultrasonic cavitation within the water column. This collapses the buoyancy structures of cyanobacteria, diatoms and other algae, preventing reproduction and reducing algal blooms by up to 98.9%.
EnviroSonic technology can also assist in reducing biofilm build-up on surfaces, helping to improve overall water clarity and reduce the conditions that allow microorganisms to thrive.
EnviroSonic technology is used in water bodies supporting cleaner, clearer water in:
💧 Drinking water reservoirs 🌿 Wastewater settlement ponds 🌊 Recreational lakes and ponds
🐠 Aquaculture and fish farms 🌾 Farm dams and lifestyle block ponds ⛳ Golf course lakes
Our units can be installed at the water’s edge, submerged, or mounted on solar-powered pontoons, making them suitable for both powered and remote locations. EnviroSonic systems operate 24/7 with minimal maintenance and no daily intervention.
By reducing reliance on chemical treatments and lowering operator time, EnviroSonic helps protect aquatic ecosystems while improving water quality for communities and industries. It provides a sustainable, long-term solution for preventing cyanobacteria blooms.
If you're looking for cyanobacteria algae control and want cleaner water, less hassle, and a long-term solution, get in touch — we’re happy to provide advice, case studies, and indicative costs.
Who we have worked with:
Where we make a difference
Lakes and Reservoirs
Ross River Dam, Townsville Queensland, Australia
Envirosonic can be set up on pontoons in either an individual unit with a semicircle (300 metre radius) or a two unit system which covers a 600-metre diameter for effective algae control.
Fish Farming and Aquaculture
Huon Valley Salmon Farm, Tasmania Australia
EnviroSonic is used in fish farms, particularly in holding and settlement ponds. Fish farming operators have also reported increased success with water clarity and no effects to fish stock.
Water Treatment Plants and Settlement Ponds
We partner with government agencies and local authorities to support wastewater treatment and consent compliance — often installing EnviroSonic units in final settlement ponds. This enables treated water to be safely reused for irrigation and other secondary applications.

Ponds and Water Catchments
Kennington Lake, Bendigo Victoria, Australia
We work with local government, private owners and golf courses to install EnviroSonic systems to control and prevent blue-green algae in their ponds and water catchment areas. Our units operate quietly and ensure the water is safe for recreation and drinking purposes.
