Low pH, Hardness, Alk, where do I start?

I just read that you shouldn't use Borax if there is copper in your pool. Will this harm my SWCG?

Borax will have no effect on your SWCG.

Borax is not an issue with copper; rather it's high pH that makes copper more likely to stain. Copper is likely to stain, even at lower pH, but it's MORE likely at a high pH.
