Water Profiles for D.I. & R.O.

Looking for a simple chart for making up WATER profiles for 6 to 8 beer styles from straight R.O. OR
D.I.
does any one have any records of this in grams for chalk, baking soda, calicum cloride, ect for making 12 gallon batches.
Looking for a simple way to treat about 16 gallons for a 12 gallon batches
This water thing is way over the top right now 
Thanks for the help

Is there a Bells Hearted Water profile
I see that there is a water profile on here
but what would be a water style for Americam IPA like Bells
I have made two batches , one with RO and 3 grams of Gyspm ,one with Well water
the one with RO turned out alot better for sure
My Well water is way to hard and alk

Just looking for a water reciept for either RO or DI for Bells
