Thanks Doc, I used the best guess chart and we went for a swim today. I told the kids that I needed to scrub and vac one more time (Just for GP) and they stood around in their goggles and swim trunks and watched... lol.

I was wondering how long it would take (ballpark - I know it isn't an exact science) for the chlorine level to drift back down to <10... I am using the dilution method and it is still out of range on a 1:1 but shows up on the 2:1 test. I have spent a ton of money on the pool (new grids, new vac hose, new this, new that etc...) so a better test kit may be a week or so away.
