If this is municipal tap water EPA says it must NOT be below 6.5 or any higher than 8.5. And 8.5 water would suck actually. Not sure why you would ever need to raise the pH. Municipal water supplies do not vary that much, at least in the East they dont. As asked before, what the hell WAS this bucket used for ? Seems strange your pH is all over the map straight from the tap.
