why using pool PH up/down was not a good idea? I was a bit concerned about using it because it was in granulated form, seemed I had read something to that effect but than may have been concerning Ferts. Been trying to find more info using the forums search engine but it keeps eliminating the "PH" term from the words searched. Weird.

Like to find out for sure if PH down for pools can be used or not? Won't attempt using it until I know for sure especially since you have recollection of it not being a good idea.

Thanks
peace
