Went ahead and opened pool, water temp is hovering 58-60 degrees, as i said in earlier post, its crystal clear.
uncovered, got pump going, topped pool off and ran pump for about 4 hours, enough to flip pool ~1.5 times.
Sat overnight, just got through testing:
CYA - 35ppm
FC - 8 ppm
CC - 0
pH - 7.7
TA - 90
CH - 170
according to pool calculator set to TFP recommended goals, I should be between 30 and 50 on CYA
Last year I was wayyy high at 80 and I just let it be and used more chlorine.
now this year im on the lower end of the spectrum at 35.
its it better to be closer to 30 or 50?
or should I just leave it alone?
