Interesting....thanks for the reply. The pool I'm looking at is a 30' round above ground Tahitian which is made by Wilbar. It carries their 2nd best warranty...lifetime on walls, and 60 years (5 full) of other parts. However, it clearly states, "Salt Chlorine Generator Systems & any other like system that uses salt to purify the pool raises the risk of
corrosion substantially.ALL WARRANTIES ARE VOIDED IF SUCH SYSTEMS ARE USED!"

I don't know why it's such a big deal, it's heavy gauge steel with their plastic coating on the walls, etc.

With the automatic chlorinators, don't they have one that uses liquid chlorine instead of the pucks, or does that automatically become an injection system?
