Getting back to the original topic of this thread, which is what are the downsides to salt pools, I am curious if Australia, which has been using salt pools for about 30 years now, has modified their construction techniques or has had problems with corrosion, expecially in some of the older pools with SWG's. Also, I believe that many of the pools there use a much higher salt concentration than we do in the U.S.
I think that finding out this info would be most useful.
