Hi, Brian,

Yeah, that's a pretty easy one. My CYA has disappeared the last 2 seasons as well. Some folks dont have that problem (the "chosen ones", no doubt ) but it looks like you and I are stuck.

Solution is easy as well....add the CYA per your SWG's recommendations. It'll probably be somewhere around 60-80ppm.

Two other thoughts:

I don't think temp will significantly affect your tests...could be wrong..anybody have any thoughts?

Secondly, TC is the addition of FC and TC. So if FC = 1 and CC = 0, then TC is always the total of those two....1
