Please forgive me if I missed this, I really did try to find the answer first...
After a very long SLAM to convert from using tablets to the BBB method, for the first time today, my CC is 0.0. Don't I wants to between .2 and .5 or is zero okay?
Ph is 7.5
Fc is 7.2
Cc is 0 (I did it twice)
Alkne is 90 (only came down 10 after adding muriatic acid to lower ph)
