'We have been using this system from Ultramins since February 2022. The USAF™ ultrasonic units removed our algae and biofilm in all our rainwater and drain silos within 1 month, the water has been much clearer since then.
We also know that cucumber fur virus (CGMMV) is no longer spread by our recirculated water as it normally is. We still had some virus, but it remained very localised while all our plants got their water from the same source.
Other positives are that this system is maintenance-free and consumes little power.'
