The pool and I are no longer friends

I think, it's said you will lose about 30% off FC from UV burn off first day coming off of a slam. So, I would think you'd come down somewhere between 5-10 ppm today with a lot of sun. That's totally a guess tho based on something I've read before.
That's exactly what happened for me.
