Hi Nick;

I have a perfect solution for you -- costs nothing, and will help your pool run better: just turn the ozonator off, and tell your company to come get it!

They are almost completely useless on outdoor pools, and the UV based models with an air pump tend to make it hard to maintain alkalinity or pH. (The little diaphragm pumps sometimes used can be quite loud).

By the way, if the company is who I think it is, you need to know something else: the ONLY "chlorine-free" sanitation system legally available in the US is Baquacil or the other PHMB based copies. Without exception, every other claim to provide a "chlorine free sanitation system" I have seen is dishonest either because it's not chlorine free (like salt or bromine systems*) or because it's not a sanitation system (like copper or 'mineral' systems).

There was briefly an EPA approved silver based system (Sildate by N Jonas) but I'm pretty sure that's no longer being sold.

If your company claimed -- in writing -- that they were providing you with a chlorine free sanitation system, I'd love to get a copy of that claim.

* It is possible to have a bromine system that is bromine only, but this has been rarely done except in spas. In any case, bromine is still a halogen oxidizer like chlorine, and the 'toxic effects' of bromine are often considered worse than those of chlorine -- but they are seriously overblown in both cases.
