Sunday 7 am test results were FC = 7 and CC = 0. I haven't backwashed today. If/when we are ready to increase the CYA--yes, I want to get to 70 - 80--I have dichlor and stabilizer/cya so can go either way. Before you suggested the dichlor, I was planning to use CYA. Dichlor has not been on my radar previously. Plus CYA seems more efficient based on the ratios you gave.
So, should I backwash first? then test cya, pH and TA at the same time then increase the cya then the TA then the pH???????
