Ugh. Poop in the Pool

[Nightmare]

OK, this should be the last post on the topic.

I just tested the FC again and it is down to 17 ppm (CC is 0). It was a warm day (90) mostly sunny with some wind in the afternoon.

Is a 13 point drop in 1 day normal? Will it stop dropping once it reaches the proper level of FC for the CYA in the pool?

You really need to do an overnight test. Too many variables in 24 hours.

Nightmare, that is the experience I had. No harm in doing another overnight test though.

FC held stead over night again

Night - 14.5
Morning - 15.5

CC - 0

I guess I'll see what happens today with the sunlight.
