I opened my pool last Saturday and had to slam until thursday when i had clear water and passed the overnight chlorine test. When i was done my fc was around 12 on friday morning. I have yet to add chlorine and my fc is still 7 (my target FC) is this normal? My cya is low around 30-35 and the pool is in direct light all day (in the process of raising it to around 60). Not that i am complaining haha, just was unsure what a normal fc loss should be.
