Due to a pump outage that lasted 10 days, my pool became a pond.I've tried to SLAM it, but CYA went to high (100) and I had to drain and refill.
Starting values after refill were:
FC 1.4
ph 7.5
TA 145
CYA 50
I've raised the FC with bleach 15%, and then I've started to lower the TA. My first shot has been to reduce TA by 20, so I've added 4,7L of Muriatic Acid.
After that, surprisingly, pH was 7.0, but TA was 153! Checked three times!
So, either the starting measure was completely wrong, or something strange happened. Do you have suggestions?
What should I do now?
My measure kit is the Lovibond Scuba II photometer.
Pool is 94,000 L , vinyl.
