20x40 pool....3.5 ft - 8ft vinyl.....400K BTU Heater
water temp about 70F
FC = 5
CC = 0
TC = 5
Ph = about 7.3 or 7.4
Alk = about 140
CYA = 30
Cal = approx 180
According to the "Best Guess" Chart, I need to be between 3-6ppm for FC.
I'm assuming that CC= 0 is GREAT, which means ALL my CL is being used to sanitize.
What level should I maintain FC...is it between 3-6ppm?
When I measure using the yellow "stuff"...Cl seems high...I'll assume this is okay since its all FC?
