Just my two cents here.... (BTW, I am more alert now!!!)

I don't know how you got a CYA reading of 35; a guess, I guess. However, I would caution against raising your CYA too much higher. You are in a Northern climate and don't have a salt water generator. I am in IL, also SWG-less, and like my CYA around 40.

Simple thought I USUALLY keep in my brain:
Borax: raises pH
Baking Soda: raises TA
Washing Soda: raises pH and TA
It's more complicated than that, but it gives me a starting point.
