Hmm Calcium is tad high?

My Ca was over 500 and I ended up removing the sand bed in one large slab. There's no need to run Ca over 400, and I imagine it would take some work to get it that high.

Agreed. Good way to precipitate the calcium and alkalinity out, especially if the magnesium is low as well.
