Like I said I really don’t know what last night was. 27 to 31/32. No idea cause my tests were all over the board. This morning I know I was at 27. When I got home I know I was at 15.
12ppm is a lot to lose in 8 hours 
Maybe your CYA isn't as high as you think it is? Did anyone swim today?

No one swam. No one home. I tested it this morning. It’s 60 but I treat as 70 to be safe. Maybe it’s 50. I’m horrible at that test but I’m confident in 60 but like I said 70 to be safe for fc calculation.
So am I not safe then? Crystal clear water. I don’t want to do an overnight test cause I know I’ll still be above my normal value I keep so was worried about user error.
