hi,
I have a 35,000 gallon outdoor, inground, gunnite pool with liners on the side, in hartford, ct. The pool was constructed in the 1970's by the previous owners. My equipment has expired and the pool has been closed for a couple of years. Looking to reopen it this year and have been advised to consider a salt water pool for it's ease of use and lower operating cost.

Although my return in pvc piping, some of my other pipes are 1.5 inch probably galvanized steel. Wanted to get an idea of my treatment options and the cost of replacing the pipes.

thanks
Al
