Question on proper levels for CH

[neatoman]

Getting ready to close my pool this week. I'm in central connecticut. I'm curious how the levels look below and specifically if the CH level should be higher.

Water Temp : 74
FC : 3
TA : 90
PH : 7.5
CH : 220
CYA: 45

Thanks

Your CH is ok at the low end.

Your CYA is 50. We round up. If the dot disappears between 50 and 40 we round up and call it 50. You can't eyeball between the lines since the scale is logarithmic, not linear.

What is the CH of your fill water?

thanks for the info on the CYA. When you say fill water, you referring to the water I'm adding to the pool from the local town?
