Thanks everyone. I'll stop any calcium dose and hopefully it will come down a little over the next few weeks while SLOWLY stepping up the alk a bit at a time.

I don't have test kit for Mg, never thought it was very important (since my Calc is high).

Thanks for the tip with baking soda, I had heard some folks say its better for freshwater than salt, but if other folks are using it, then I will try this as well to save a few $s.
