Unless you have nitrates or phosphates in your raw water simply mixing
the RO water with the raw water will work fine.  My water isn't quite
as hard as yours and I find that about 50/50 mix works. In any event
you don't need to mix it exactly - just check the hardness of you
aquarium water occasionally and adjust the RO/raw water ratio. 

I store the water in one of those 18gal Rubber Maid Storage Bins.
Before making a water change I add warm raw water to the RO water. For
make up water I just use the RO water but because I not adding that
much I find I don't need to heat it
