Yea I was reading something about OZONE being useless if the pool is not like $100,000 for the setup to work. About the naturalII I just understand its minerals that cycle through the pool. Sales rep says its just like the spring water that flows in the mountains and claims that is why no alge is effected by it and it prevents it.

I might just do the old school pool chlorine, I mean since my kids, wife and I does not effect us.
