Only one thing to add:

If your FC is 3 and your CC is 1 then your TC MUST be 4, not 3.

If you use the FAS-DPD powder test, then don't rely on the PS-200 TC test--that's a quickie test when you don't have time for FAS-DPD (like me, this morning! )

Always and forever: TC = FC + CC By definition. If you know 2 of the 3 , you calculate the third.

With a CC of 1 you need to shock your pool to clear that. DaveS gave you the #'s

By the way, GREAT name (even if you do spell it wrong! )
