Your results are pretty good. I recognize you got your TC result from the OTO test......not by adding FC + CC.

Many, if not most, new kit owners do just like you and go right down the tests one by one (I know I did) and end up with a TC result that is different from the total of FC + CC in the FAS/DPD test.

Most of us don't report both tests...just the FAS/DPD test and let the reader do the math to get TC.

Your salt seems a little high....most SWG's seem to require 3000 - 3600 as ideal but I am not an authority by any stretch....it's just what I've read from other SWG owners here on the forum.

As watermom indicated, don't let your pH slip up into the 8's.
