I had a valve problem and had to shut er down for two weeks. I just got the bottom vaccummed and the valve is now working correctly. Haven't received my taylor test kit yet, but the "evillll pool store" tested my water for me and here are the results

FC=.1
TC=.8
CC-.7
ALK=152
PH=7.7
CALCIUM=222
CYA=100
TDS=1,200

using the best guess chart, I know that I need to shock to 25 and then maintain a minimum of 8 fc and a max of 15 fc. My question is how much bleach will it take to shock to 25? My pool is 16 by 32 & holds abot 18,000.

Is there a formula to determine this?

Thanks.


UPDATE:

I used the bleach calculator and figured that I need approx. 7.5 gallons of bleach to get to 25ppm. Is that a correct?
