For those who have a pool cover, I'm curious what your FC loss per day is?
I've put a clear pool cover over my pool, mainly to prevent evaporation and FC loss. But I still have quite a bit of FC loss per day.
Before I installed the pool cover, I was loosing 4 ppm of FC every day. Now with the cover installed, I'm losing 3 ppm of FC every day. I was hoping for better results then that.
I know nothing is eating up the chlorine, as I've done an overnight hold test, and only dropped .5 ppm.
Here is my complete test results.
FC 6 (Before adding bleach. I try to keep between 8-10 ppm)
