TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.A p.s.: I also appreciated the graphic you provided on the half-life curves at various levels of CyA. I had, however, already seen that...
-
TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.I appreciate your information on the CSI/LSI. Provides more detail on how it came about and how it applies. Thanks. After the county...

TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.I leave the measuring of grass heights and weed counting to the owners. Most of them could do with more outdoor exercise anyway. I just...
-
TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.Once again, Oops. Correction: "Now ask: What percentage (ratio) of Free Chlorine will be destroyed by the very same solar UV on December...

TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.Thank you AUSpool for your input. It clearly shows that you do understand the fundamental issue. Part of the following is an exercise in...
-
TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.To AUSpool: Yes, we are "constrained" in our allowable operating conditions. To be within Code in Pima County, AZ, operating a...
-
TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.I totally agree. I'm not trying to achieve absolute accuracy in my own calculations. I don't know that anyone at all has documented...
-
TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.My thanks to AUSpool and mgftp for your comments. The .04 was erroneously entered by me, when I had intended .4. It's not "somewhere...

TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.Oops. That should have been .4 ppm FC loss, not .04 Transcription error.

TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.My apologies to any all who have followed my postings with resulting confusion and/or frustration with my ignorance, sometimes amplified...
-
TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.It is proportional. FAC Molar concentration (Fraction) * Total Available Chlorine (TAC) PPM = FAC PPM. I'm not sure where you're trying...
-
TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.I guess I didn't do a good enough job of presenting my information clearly enough in my initial posting of my "Observations". I did in...
-
TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.Also, am I breaking this forum's protocols by using my real name? At 75 years old, I don't really care. But . . . I'd rather not be a...
-
TTom ONeill replied to the thread CYA vs UV Chlorine Loss Test – Observations.Oh - And the doubling and quadrupling of the FAC molar concentration matched the doubling and quadrupling of the FC losses in the as985...
