Ben and Chem Geek you both rock!! Actually makes complete sense but that would be because I was a marine bio major with serious chem background and now I'm a physician assistant and live in the scientific world. That is exactly what I thought and explained to my pool guy. He didn't understand prior to our conversation that the tests measured bound and unbound (I made a darned good guess, but based on the reality of binding to stabilize I figured that had to be the case). He had always just done the usual "Chlorine lock" crap. Referenced this forum so maybe I have created another convert or maybe he was just thinking I'm a lunatic! ;-)

Either way...pleasantly happy with my first swim in a FC of 9 and found it much more comfortable than lower levels at other pools. THANK YOU POOLFORUM!!!!!!!! Now off to read all the referenced materials. I would like to speak with authority when people question my way of dealing with my pool this season until my CYA levels are lower and frankly from here on out.
