I've been struggling to get my CYA up to 70 or 80 since the pool was built. My latest test results are the following:
FC - 2.5
CC - 0.5
PH 7.8
CYA 50
TA 90
I should have my CYA up to 80 with the amount of CYA that I put in. The highest I have been able to test it is 65 maybe 70. We had about 3 or 4 inches of rain and I did a long backwash 2 weeks ago - so could that explain why it went from 65 to 50? I'm really not sure what else I should do. I've followed the extended test instructions and have done the test several times.
