Experimenting with CWT Vulcan
Recently a CWT Vulcan system was installed on a pipe in the building where I live and the calcar that I had watched being deposited in a kettle stopped depositing, and even started to disintegrate. Within a week, or less the calcar almost vanished.
To over-simplify it, you wrap a coil around a pipe, with an electronic ciruit board and it uses electric currents, through electrophoresis to take calcium and magnesium from complex to simple structures.
