Thanks for your reply Janet.
After I got those numbers, I shocked with 2 lbs of HTH Super Shock and Swim, so hopefully, that brings my chlorine up beyond 8/10, no?.

Oh, sorry, I missed that the first time I read your post. That probably did bring it up beyond 8, but you're going to need to keep it there, at least 8, for as long as your CYa is that high. Not sure what the chlorine source of Super shock and Swim is, but if it's dichlor you need to stop using it because it raises CYA even further. You're probably okay for awhile if it's cal-hypo, but when your calcium numbers start getting past 200 or so you'll need to switch to bleach or liquid chlorine.

Super Shock and Swim is Cal Hypo.
Actually, they said my calcium was low - so that might actually prove beneficial!
My Taylor 2006 kit just arrived 10 mins ago! No more pool store!
So, the store told me this am that my CYA was 100. I did the Taylor test for CYA. The first time I did it - my CYA registered 40. I had some water left and tried it again. I didn't have enough to make the dot disappear, but I could still see the dot when I ran out of treated water - and that stopped at 60. I think the kid at the store did it wrong!
So, I did my chlorine - this is where I might be in trouble. My FC was 60 and my CC is 4.5 (I shocked at 10am with 2# cal hypo to scare out any metals).
Do I have a new problem on my hands because of the CC?
Try those chlorine test again. I can't imagine that your FC is actually 60 and CC is 4.5.
Also, is this a vinyl pool? (I can't remember from your other thread.) If so, you don't need calcium.
I goofed Watermom! I misread the instructions and multiplied by 3 not 0.5 (don't ask). So my CL is 15 and CC is 4.5. I read horror stories about getting this balanced (someone used over 100 gallons of bleach.
I do have a vinyl lined pool (AG 24')
I did the rest of the testing, too.
FC - 15
CC - 4.5
pH - 7.2
TA - 60
CA - 50
CYA - 50
My only concern about my numbers from the Taylor test is there were 2 incidents where the color they described was not the color I got - but adding more reagent didn't make a diff. Example - in the TA test, my color was supposed to change from green to red. I got more of a magenta. The calcium test said solution should turn blue. I had more of a indigo/purple.
With a CYA of 50 - I removed the CYA sock from the pool (this am pool store told me my CYA was 100 - but I did Taylor twice and got 40 and 50 respectively).
For what it's worth, the color palette you describe for the end-point of the Total Alkalinity (TA) and Calcium Hardness (CH) tests match that of my testing.
TA test titration ends in a dark magenta (not red)
See http://gizmodo.com/assets/resources/2007/11/magenta.jpg
CH test titration ends in indigo / lavender (not blue)
(I'm not aware of any particular reason for these discrepancies and have tried performing the tests in every way recommended by Taylor and others, but the results are invariable and have been for 3 years.)
