I was lost but now I'm found?(forgotten password made me ?)

Here are my current TF 100 tests results
pH 7.5
FC 3
CC .5 or lower, test tube needs scrubbing
TA 60
CH 150
CYA Don't know, ran out of reagent

When pool was opened, I had 11 CYA level according to pool store test, so I did add 2 (4# bottles) at different times. I do get a reading on a test strip but no idea what level is. Have trichlor pucks in a floater. Only adding cal hypo about once a week, very little being used. Pool is very clear, brush and vacuum once a week. Bather load on low side this year. By looking at recommended levels in pool school for a vinyl pool, my numbers look good. Wonder if I can buy cya reagent alone, I have plenty of the other solutions. Would you recommend any additions to my pool?
Thank you for any advice or input.

R-0013 CYA Reagent (8oz)

Your FC is on the low side. You added 33 ppm CYA - so assume 40 for now. Use the FC/CYA Levels

Amazon sells CYA reagent in 16 oz bottles.

I assumed that 40 was my CYA level after the last addition but that was added 6/14. I have had to add water to my pool and it's gotten rainfall. Would I be correct by assuming it's still around 40?

Unless you overflowed at least 20% of your pool volume, then yes, assume 40.

If you go to Tftestkits.net you can buy all the refills you need and not be dependent on unreliable strips.
