Higher Calcium Numbers Seem to Control PH better

I respond to this issue in this thread in The China Shop since it's a technical response.

Thank you both for your responses, they are very helpful.

I do not at the present time have any issues with FC dropping, it stays remarkably static at around 5 even with a cYA of 30-35.

I use to use chlorine from WalMart and adjust the acid manually. Now with the SWG I do not have to do that. I really enjoy the fact that the in-line chlorinator does that for me as I cannot always attend to the pool when I travel for a day or few days a week. So for me it was a good purchase.

My main issue was whether or not high Calcium (575-600) numbers and a lower pH of 7.4 was a good idea. From what chem geek states in the"China Shop" post it was not such a good idea. So I will adjust to Calcium 375 and a pH of 7.5.
