I am having a 17x31 in ground installed in Pensacola Fl. to be swimming by Memorial Day. I am also having a Heat Pump of 125,000 btu's with Titanium coils. Question I have concerns the 'Ozone' system, or Salt water system. I have been advised that both are good-depending on which salesman I speak with, but I can't find a good comparison anywhere. Can you help?
