This is my first full season with the pool. It was completed last august 1 and used for approx. 1.5 months. During completion the in line chlorinator ran fully open and cya was showing deep color on the test strips (thats all the "testing equipment" I had at the time)..
My water is not circulating at present but I did testing to get use to my new TF-100 Xl kit that came in. here are the numbers..
cya-- 70 (test ran 4 times)
cl-- less than .5 (cl/ph ran 3 times)
I have algae starting on the bottom but water is pretty clear at present.
I have plugged these numbers into the pool calculator to get the amount of chlorine I need to add to get to shock level with a cya of 70.
Should I use these numbers to start adding chlorine at the very start of the water circulating or should I circulate first then test again and use second set of numbers to base chlorine addition ? I'll be opening friday. Should I get the chlorine up to the shock level then adjust the other catagories later?
In case the stats do not show up in signature,,,,,,

Glad I found TFP before my first full season starts. The standard answer I've received from most sources is "shock regularly" and use pucks. After reading the great advice here I now know that's the route to problems in the future.
