Pool is now full. I've been adding small amounts of chlorine over the past few days while it fills, both tri-chlor pucks and some cal hypo. Chlorine still tests at zero.
PH is 7.2 which as I understand is on the low end, but I plan to add a bit more cal hypo which might bring it up a little, or at least hold it steady.
TA is only 20 ppm. I've added all of the sodium bicarb that I have, about 30 lbs. We'll see if that makes much of a difference, I'll test again tomorrow.
I've added a small amount of cal hypo and one more tri-chlor puck today. I don't want to get too far ahead of myself as I'm under the impression that I need to get the TA under control before I move forward.
Thanks for your help and replies.
