CYA 100 still
I am ready to close today and went to pool store and told them I use Liquid only, So I got 2 bottles of 12.5 'Super Shock' they told me to put in for 10,000 gallon pool. Doing the math that wil raise my FC to approx 25 ppm to say 32.5, above the shock of 25. Will this bleach my liner? Should I cut it back a little to 1 bottle? which would raise me to about 20? I never closed BBB before always used back shock.
