Found this old thread via a google search, so I thought I'd resurrect it since I'm working on a calculator for reconstituting RO water.

Can anyone double check my calculations?
I've double checked the dose and resulting ppm of ca, mg, and K on APC's fertilator.

However, my doses don't match the shortcut from this thread

The numbers for a 4:1 ratio are:
For 1 dGH per gallon - 0.07939 grams CaCl2*2H2O, and 0.03327 grams MgSO4*7H2O (epsom salt).
My spreadsheet is here:
