I came across this as a listing on EBay trying to set up distribution. This sounds almost as hoaky as the magnets in your diesel tanks trick but I'm curious to know if anyone has any experience with this thing. The writing sounds like a bad translation even though it says it is an Australian product.

The ASM Marine Sonic device emits special formatted range/pulses ultrasonic waves into the water.

The transducer produces a complex ultrasonic pattern that results into bursting of the small vacuole in the centre of each algae.

The resonance results in overpressure in the vacuole that cannot be withstand the membrane bursts.

Most kinds of algae are dismantled already after seven to ten days. Other kinds detach after six to eight weeks when Marine sonic is installed
