I think the idea is that the chlorine we put in our pools, thinking the BBB troublefree way, performs two functions. Sanitation & oxidation. Ozone is purely an oxidizer, so it "relieves" the chlorine of the oxidation function.
However, the BBB gurus have noted in another thread that you can't tell the chlorine not to oxidize CCs & it has no idea if there is an ozone generator at the equipment pad. They have also formulated only a small amount of the chlorine you put in your pool is to provide the oxidation function.
But I've seen guys with numbers like FC: 0.5, CC: 1.5 an ozonator could make that FC: 0.5, CC: 0.0 If FC: 0.5 is enough to sanitize a pool, then the pool is still safe. I know CYA makes it impossible to sanitize a pool with 0.5ppm of FC... but what if all you need to sanitize your pool is 4ppm at your CYA level, but the suggested number is 6ppm or 7ppm to provide enough chlorine to oxidize the CCS.
If the ozonator can take the place of the extra 2 or 3ppm for oxidation & you only have to maintain the 4ppm, would that be of any benefit?
At the same time, once you get your FC to the desired level... 7ppm you are pretty much only maintaining the 2 or 3ppm your pool uses daily..... so it's probably the same thing.
My point is that if sunlight/UV eats up 2ppm of FC per day, ozone is NOT going to reduce that chlorine demand, in fact it may increase your chlorine demand as noted by Richard.
My pool is used by 4kids and 2 adults, almost every day for 4 months straight. In 3 years of ownership, following BBB (I test my water daily), I have never had to shock the pool, nor has my CC ever registered above 0.5ppm. Most folks seem to think my saltwater pool is not a chlorine pool (wrong), as they state the water does not smell. I need an ozone generator why?
Listen, I understand you may have invested in one, and having it as a saftey net can do no harm, but if you maintain your pool regulary, it's just not a necessity to have a sanitary, clean, soft feeling pool.
