Need help, I think. My FC level seems to be dropping too fast. FC was at 4.6 around noon time, just checked it again 6 hours later and it was 3.4.
Pool water is sparkling clear. No visible issues at all.
I got suckered into starting my pool on Pristine Blue, but quickly changed my mind on that once I did some research, so I made the switch to chlorine, by way of trichlor pucks, and then I switched again to the BBB method. I may still have some copper in the pool from the pristine blue.
I run my filter for 5 hours in the AM, and 5 hours in the PM on a timer.
CC - under 1 ppm (test only produced a very faint, faint, pink tint, so im thinking its just over 0 but under 1)
TA - 120
PH - 7.4
CYA - 50
Above ground pool - 24' x 54" (1 month old)
Thanks in advance for any help on this.
