He said the smell is definitely like hotel but not as strong today- meaning worse yesterday. But the "taste" he's never encountered before. I thought it might be the rain - we've had some last night and early morning and the cover was open. I'll tell him it's CC and see if he gets grossed out.

Btw: I want to take is opportunity to thank BigDave and FBU and Watermom and CarlD and of course PoolDoc ( whom I didn't immediately realize was "the Ben" who championed the site), and everyone else here who patiently read through my not-so-succinct posts and helped me get closer to the finish line. I've learned so much already- thank you!!!
