If I raise my FC from 2 to 12 for my fortnightly shocking, how do I contend with the large rise in pH from the introduction of the 275 ml of 6% bleach needed?
Will it return back to normal on it own after a few days, or will I have to add muriatic acid to deal with the pH increase?
What do most of you guys do when you shock?
(P.S. I have a Spa not a swimming pool)
Thanks - D
