At what point does carbonate hardness become dangerous on the high end?

No, I did the yearly cleaning with vinegar for the pumps and skimmer which made the PH drop to 7.8. Then I had a brain fart and dosed 2 cups of baking soda to raise the PH. Didn't need the Carbonate to be raised. Stupid mistake really. But everything seems happy so I am just going to leave it alone and see if everything works itself out.

I can tell you this though... Baking soda makes your water cristal clear!

Carbonate back down to 12 or 13. Everything looking great so far.
