Hi all,

My wife and I are seriously considering having an in ground pool installed. We've talked to three different contractors and have heard vastly differing opinions on the below items:

Salt system:

Two contractors say it's great - better for the skin, easier to take care of, etc. One recommended against it and says it causes heaters to blow up, "it's not good to have all that salt in the water", etc. Who's right? My wife has sensitive skin, so, if there are no major disadvantages to the salt system, it seems worth the $1300 price tag.


Ozonator:

I currently have a portable spa with an ozonator and Nature2 and love it. Two dealers recommended ozonation for the pool, while one said "it's not really effective". Who's right?


Two-speed pump:

Here in San Diego, electricity is very expensive. I've heard that the two-speed pumps can really save on energy costs. Two dealers recommended the two-speed pump, and one said that they're a waste of money. We do plan on installing solar heating as well as a couple of "sheer descents" water features. Will the two-speed pump be pointless since the solar heating will (apparently) require that the pump run in the high-speed? What about the days in the summer where the water is already hot enough?


Solar heating system:

The concept seems very basic - put some black plastic panels up on the roof and pump water through 'em so that the water soaks up the heat from the sun. Are the more expensive solar heating systems really that much better in efficiency, or will an inexpensive solar heating system be sufficient?


Thanks, in advance, to all that can provide some unbiased opinions on the above features.
