Im going to raise my pool to shock level due to me having to leave town (see this post http://www.troublefreepool.com/insta...er-t64277.html)
Ive read the shock process, and am looking at the Chlorine/CYA chart. I see the warning about not raising FC above 5 if CYA is truly 0, which mine is. So, is it safe to put it at shock level of FC=12 if I add liquid CYA along with bleach? I would put 2 gallons of liquid CYA which would get me just over 30 and then add 5.7 96 ounce jugs of bleach which would get me at FC=12.
I would try to pour the clorox one bottle at a time in front of a jet slowly, and alternate a bottle of CYA between the first couple bottles of bleach.
