Hey Stir and Welocme back !!
They don’t themselves.
T-Sonik PW is a device designed for swimming pools and wellness centres, which can eliminate bacteria and algae, thus reducing – and in some cases, eliminating – the use of chemical products for the sanitisation of water.
So what does that mean, Stir ? It means they have a device which treats the water passing through it which very well may work. On paper, both UV and Ozone systems work. Not sure what sort of virbrations/sounds they use, Maybe they serenade the water with Sweet Caroline on a repeat loop. But without a residual sanitizer, 99.999999% of the water goes stagnant.
So you may use the system, but need to treat in full with chlorine like it isn’t there. So why get it if you still have to fully treat ?
