Chlorine Lock

[PoolDoc]

Your TA is too high, but nothing to worry about at the moment . . . except that you'll need to keep adding acid to keep you pH below 7.8

BUT . . . your chlorine is too low! Are you adding 2 gallons of bleach each PM?

If you have the Taylor FAS-DPD test kit you cannot get "FC =2 and TC=1". Perhaps you mean CC= 1 rather than TC?
Rule: TC = FC + CC. Therefore TC can NEVER be less than FC.
