Some background first... I discovered TFP this spring and opened my pool right - using TFP methods and a TF-100 test kit. Over the course of the summer, I've gotten lazy about it...quit testing regularly, just added chlorine every couple of days, etc. I'm aware that was a bad idea and obviously that's why I'm in the mess I'm in now! Which is: a couple weeks ago, the pool started gradually turning green. I backwashed the filter, brushed the pool, added a gallon of 12.5% chlorine, and have repeated that over and over...it's steadily gotten worse and is now pretty dark green. Stupid me, I didn't think to test it (DUH!) until today, and everything's off.
FC 0
PH 8.2
TA 60
CYA 0 (or at least less than 20)
I didn't check CH because I have a vinyl liner, someone correct me if I'm wrong and need to test it.
I have two questions: First of all, I thought the whole point of TFP and using liquid chlorine or bleach is because chlorine pucks have too much CYA, and it builds up in the pool because CYA doesn't evaporate? I've added CYA to the pool twice this summer (if I remember right, I got it up to 30 the first time and 50 the second). Now it's at 0 again. Just wondering if I misunderstood or did I somehow mess it up by not regularly maintaining and testing everything?
And then...do I need to adjust all the levels or just add CYA and SLAM first?
Thanks!!
