well i am draining the pool today. going to take a sample of the water today, and then after the 2 trucks and waiting overnight, i will take another sample to get tested tomorrow, unless my own kit arrives. is it possible that if my cya comes down to 100, that i could still go throught the shock process instead of having to drain and refill a second time? we do not plan on draining it again. we would rather drain it to winterize it...but it my cya comes down, i wouldnt mind shocking it if that is possible (even if the cya does not come down to 50).
in your opinion, is it rediculous to shock it before winterizing it because it is going to need to be done it the spring anyways?
thanks again, everybody for your information and patience with me. it is so nice knowing that you guys are all available and willing to help.
