What a great site - I've been looking at posts for awhile and finally got the time to register (who knew how quick it would be)!!!!! Many thanks to the ADMIN for such an informative site. Eventually, I might have a clue as to finally getting the pool water correct! Last year we bought a house with IG SWG pool. Opened ourselves (probably not a smart move) and have been having a heck of time trying to get water balanced correctly! Having problems with staining so am trying the AA treatment (for the 2nd time) and hope to resolve the issue! I'll post my ? under a new thread in hopefully the correct forum - I'm a newbie to both pools and forums. Happy swmming!
