I had been having some trouble with FC losses of 3.5 to 5.5 ppm a day. My pool is in full sun from 10 am to 5 pm. My reading on my CYA test appeared to be between 40 and 50 then. After posting my issues I decided to add a bit more stabilizer a few weeks ago. I now am seeing 2 to 3 ppm drop per day. I tested my CYA this morning and it is between 60 and 70. I have trouble determining seeing the black dot lol. I have been targeting FC at 5 to 5.5. Should I be upping my FC even though I am having no troubles?
This mornings readings
CYA 60 to 70
