I know it may be genius marketing, but I am 100% positive that my Prozone unit works to eliminate CC. How do I know? for the first 3 months of owning my tub I had my pump 1 aeration off (during my tub time I would turn it off at the end, to relax without bubbles). That then meant my 8 hours of pump run time to get the SWG going (along with prozone) was not using aeration.
My CC was stuck at 2 for a couple months, and I couldnt fix it (its under a deck so no access to sunlight).
One day I decided to turn the aeration on after I left the tub and within a couple weeks all my CC had been cleared up. It had not budged for 3 months. Now 1 month after a refill, with my aeration left on, my CC is still zero and holding there.
It may not be useful for some folks, but It certainly has use for me.
