The test sample was barely pink (after adding the 5 reagent drops), then one drop of R-0781 turned it water clear, so <= 0.5

Just had another thought : it looks like rain here. Should I cover the pool if we do get rain? I've never had rain water in my pool before ( another big rule from the pool installers which I've always adhered to- always cover the pool when it rains.... Rainwater is bad).

Huh???? I OPENED mine at 5-ish this morning so I could get the rain in my pool.

Oh- I see. At night, dose the pool with bleach to get a FC of 30, wait an hour and THEN take another reading for the night. Sorry, my brain is slow.

Yes! You need to make sure you've reached the target FC. Under shock conditions you don't want to make assumptions. (Once your demand is gone, you won't have to do this).
Have you checked your CYA lately? BigDave mentioned the possibility of some conversion of CYA and I don't have time to back track to see when you last checked it.

Last week (august 11) my CYA tested at 150. I typically do the test 3 times and average. (since it's a more subjective test than most- i think). I have not added any hose water since last week, but I will test it again today.

If you tested CYA on August 11, no need to do it again. Just wastes reagents.
