Hi there! I am new to TFP and a new pool owner. We set up our new pool on 7/13/13, added the salt the next day, waited 24 hours with the pump running and then turned on the SWG per the instruction manual. I bought the cheap 3 way test from walmart you all recommend while I wait for my TF-100 to get here. My question is, what is total chlorine?...that is what the test results give me, not FC like your article says to be testing for. Or am I confused? lol Thanks in advance for your help!
