pH battle:
-Pool Math-how much acid to add to get it down to 7.8
-Add said amount with the pump running on high and brush at least that area
-wait about 15 mins and test again
-rinse and repeat until you get a reading in the 7s!
Good luck and use great care while handling the m.a. Make sure to have something over your eyes. Take your time and don't spill any on anything. Have a hose standing by to rinse anything off just in case there is a spill or such.
