Thanks, Denny! I appreciate your info.

I guess my question would have been better worded if I'd asked "do I need to bring the pool to shock level after this?" I couldn't see anything in the dark last night to add and test FC shock levels, but I do test daily and have been consistently within Ben's recommendations for FC on the Best Guess chart. It's going to be 102 today so it will be torture trying to keep the kids out of the pool if I have to bring it up to shock level today.

Without getting graphic, the accident was mostly contained. I think I'm going to boost my FC up to a max level this morning and let the kids swim later in the day. Anybody have concerns about this plan?
