Some comments on your company and product may be found
here. Vitalized Water Products appears to be rebranded from Nilemark Water Processors. If the product works so well, why not have an independent test lab (with a good reputation) try it out? Why rely on a smattering of testimonials (see
here for example, from a related website
gfxtechnology(dot)com).
In the FAQ
here, you say that VWP "crystallizes the minerals in the water reducing hard water scaling problems". In other words, IF the water is already super-saturated with calcium carbonate, THEN the technology could (I'm not saying it does, but giving you the benefit of the doubt) promote and accelerate crystallization (otherwise known as scaling). If this occurred, then your unit (or the pipes where your unit is attached) would build up scale and would need to be replaced or cleaned often. Where does all of this crystallized (i.e. solid) go? Also note that even causing crystallization will still leave the water near saturation of calcium carbonate -- it could still scale if such water were raised in temperature or pH downstream, such as in a gas heater or an SWG cell in a pool.
By the way, it's not bacteria that consumes chlorine in pools -- even extraordinarily low levels of chlorine will kill most bacteria and prevent uncontrolled growth (unless biofilms have already formed). Higher levels of chlorine relative to the Cyanuric Acid (CYA) level are required to prevent algae growth unless a supplemental algaecide (or phosphate remover) is used. Also, most chlorine loss occurs from breakdown from sunlight in residential pools (in commercial pools, it's mostly consumed from the high bather loads).
