Yea we talked with a pool store today and they said it would rust the metal top of the pool after a few years of use. We're looking at buying a professional pool now there not to expensive. Plus the cost for the saltwater system at this time will be to expensive with the cost of everything else. Thanks for all the help I do appreeviate it. We're going for a 18 foot pool since that's basically all the extra room we have without really doing some ground removing living on a good size hill does have a down fall.
