Just recently completed a major home rennovation that included some work on an existing pool (resurfacing, replacement of some plumbing and equipment, etc.). When we contracted for the pool work, we were intending on installing a salt water system (our kids use pool a lot and my wife strongly prefers salt water pools because of the reduced irritation to eyes and skin). We have our pool contractor ready to install the salt water system, but the guy who services our pool has strongly cautioned against salt water as he warns it will quickly corrode our filter and heater. He suggested we rethink salt water and if we really wanted to go with something different than the traditional chlorine-only approach, we should consider alternatives. I went back to the contractor to explore other options and said he had recently installed a UV system (DeltaUV) which he recommended as a good alternative. I checked it out on-line and it looked good to me, so I mentioned it to our pool servicer who said he never heard of it. He in turn recommended either Ozone or ionization. I've tried doing some research on-line to weigh the pros and cons of these different alternatives and my head is spinning, as most of what's available on line is information from various manufacturers and suppliers. At this point, I'm wondering if I just need to tell my wife that she'll have to give up her dreams of reduced eye and skin irritation and stick with chlorine; or if one of these other systems is a practical and effective solution that will keep our pool water sanitary without being as harsh as a pool purified only with chlorine. Any advice on this front would be greatly appreciated!
