Hi,
Went to the pool store on Friday my numbers were :

FCL 0

TCL 0.4

CC 0.4

PH 7.3

ALK 0 !!!

CYA 55

So I put in Alkalinity up to raise ALK And I shocked the pool with 8 gallons of 6% bleach.I also put tabs in the chlorinator and turned it up.

Today's numbers were:
FCL 0.0

TCL 1.2

CC 1.2

pH 7.7

Alk 89

CYA 70


Pool Store recommended I use Sodium Hypochlorite 12.5 % to shock , I bought 2 five gallons jugs , how much should I use at one time to shock the pool ?? He suggested 5 gallons tonight, retest tomororw morning and see from there .i want to hit the 20 ppm mark but did not receive my FAS-DPD test kit yet .Any Advice how to proceed.

i have used this pool store for the last 5 years, the other pool store I went to was a new one .I'm gonna stick to the old guy but his chemicals are very expensive .THANKS
