Or add it, let it circulate for a couple of hours, then test....it'll give you at least a ballpark.

OK. Already got yesterday's late PM reading. Added chlorine last night (shooting for FC 6.8 as per chem geek's chart) and measured this moring (pump worked non-stop.) Will measure again at eve and will post all numbers. Thanks
