When I go to pool math and enter 16 oz of trichlor it says the effect on PH will be .59.
Does that mean if my PH is 8.2 after the addition it will be just over 7.6?
Or does it mean .59 of .1 and my PH will only drop to like 8.1?
I added trichlor shock last week ( my CYA was actually down to 25 where it was close to 200 two years ago. Yea!) and it seemed to have little effect on PH
