Using PPS Pro with RO/DI water.

Looking for a DIY Recipe for re-mineralizing RO/DI water. Found the recipe below, see chart/link.

Question: Can CaSO4*H2O2 be substituted for CaSO4? Seems as if gypsum is much cheaper and easier to find than pure CaSO4.

Of course, any other tips on this topic appreciated.
