Getting ready to close our pool so I need to work balancing the water. Today the water temp was 56 degrees and I used a Color-Q Pro 7 for testing. Readings were as follows:

CL 7.66

TCL 7.93

PH 7.6

ALK 65

Hard 455

CYA 43

Salt 2600

Knowing the CL & TCL are too high I turned off the SWG. As for the ALK should I raise it before I close or wait until I open in the spring? I was a bit surprised to see the hardness reading of 455, same question, should I lower it prior to closing?

Thanks for your help
