OK, everyone....good news! After 40 hours of ensuring shock level and checking every hour, i passed the OCLT!!
I had 21.5 ppm last night at 10:00, and still had 21.5 ppm this morning at 5:30. Also, after dropping in the 5 drops of the R-003 test for combined chlorine, the sample remained colorless! So....the way i read this, I have no combined chlorine.
I want to thank you all for the help.
My only remaining question is how long should I wait to worry about PH, alkalinity, and all that. Reading through this site, I found that shocking the pool can affect the other water measurements.
Thanks again for all the responses!
V/r,
Don
