Frequently Asked Questions
Does EnviroSonic kill all types of algae?
EnviroSonic disrupts the reproduction of non-motile algae—including blue-green algae. This prevents unwanted algal blooms, even in warm or nutrient-rich waters. However, EnviroSonic does not completely eliminate all algae, as many types occur naturally and play a role in the ecosystem. Once the system is turned off, algae may resume rapid growth under the right conditions.
Do you use chemicals to kill blue-green algae?
No. EnviroSonic is completely chemical-free. In today’s world, chemical treatment is unnecessary and often harmful. Copper-based algicides, commonly used to control blue-green algae, are:
Toxic to non-target species such as zooplankton, invertebrates, and fish
Destructive to beneficial bacteria
Persistent, accumulating in sediments long term
In fact, many countries have regulations restricting algicide use due to their environmental risks. According to Water Research Australia, copper sulphate should only be used minimally and as a last resort—and even then, only in specific water supply reservoirs.
EnviroSonic offers a proven alternative. Ultrasound technology has been used since the 1970s and is safe for humans, animals, and aquatic ecosystems.
How does EnviroSonic control algae?
Ultrasound algae control was developed in the Netherlands in the 1980s. EnviroSonic emits ultrasonic waves (20–60 kHz) that travel at over 1,400 metres per second. These waves create cavitational stress on algal cells, disrupting their structure without causing full cell lysis—avoiding the release of odours, toxins, or unpleasant tastes.
Is EnviroSonic safe for people, the environment and animals?
Yes. Our systems are safe for invertebrates, amphibians, fish, and even bats. We’ve also observed positive impacts on wildlife near EnviroSonic installations. For example, at Grassy Dam on King Island, blue-green algae was brought under control—and the resident platypus population noticeably increased.
How long do EnviroSonic units run?
EnviroSonic units operate continuously—cycling for 1/3 of a second, every second, 24/7. This constant operation is key to preventing algal blooms, which can return if the units are switched off.
To support ongoing performance, our systems can be remotely monitored using GSM technology—ideal for regional or remote locations where regular site visits aren’t practical.
What costs are involved with EnviroSonic units?
EnviroSonic units are highly energy-efficient. Our ES300 model uses just 100 watts of power, costing around $250 per year to run continuously on mains electricity. Solar-powered systems incur no running costs at all which ensures your sustainability team will be happy to promote the success in energy efficiency.
We also offer optional remote monitoring and scheduled maintenance—tailored to the size and location of your site. Contact us to discuss your needs.
How are EnviroSonic units installed?
We provide a full installation service, especially for our solar-powered ES300 pontoon systems. These require secure anchoring or tethering and need to face north to ensure optimal solar performance. Our installers are qualified electricians experienced in water-based installations.
For the smaller ES50 units (which use mains power), many customers—such as farms, fisheries, golf courses, and councils—opt to use a local electrician. We provide detailed a installation instructions and can guide you via phone or video call to help determine the best placement for your system.
How often do EnviroSonic units need maintenance?
We recommend a physical inspection every twelve months to ensure everything is operating efficiently. Remote monitoring is also available for real time reporting, especially for sites in hard-to-reach or environmentally challenging areas.
We offer scheduled maintenance contracts to help keep your system operating reliably year-round.
