I have had my pool for about 6 years now and have always relied on the pool store to sell me what I needed (or what they told me I needed.)
Just opened it up today -- water looked really good. Used the TF100 and came up with this:
chlorine = 0
PH = 7.5
TA = 180
CH = 310
CYA = 100 ish
Using the pool calculator and what I read in Pool School, I had some left over PH Reducer (dry) and added one pound, turned the return up to break the surface to reduce the TA. Then I put in 96oz of 6% Great Value bleach, which should have gotten me to a chlorine of 7 -- but I'm not really sure if I'm using the pool caclulator correctly.
I remeasured the chlorine and PH and got: 2 and 7.2
Looks like I going in the right direction, yes or no?
