Water Chemistry

I came across some old threads on water for brewing coffee. This is an area I have some experience in as I build my water for brewing beer. The difference between good beer and great beer often is the water. Different beers need varying salt and pH levels to achieve the proper flavor profile.
I saw a thread where it was recommended that if your tap water was unsuitable then RO or distilled water with 30ppm calcium carbonate was advisable. It brings the water into the correct mineral ion range and has no ill effects on scaling in the boiler or otherwise. My water is less than ideal, ( too soft ) so I'm experimenting with the chalk and RO water.
One thing often overlooked is that calcium carbonate will not go into solution unless carbonic acid is added:

I'm giving it a shot, actually several as I always drink two in succession.

Thanks Ginny, some great info.

Well, I dissolved some calcium carbonate (chalk) using co2, reverse osmosis water, my cabonator cap and a 1 liter soda bottle. I used a concentration so 1/2 cup of the chalk solution gives me about 50ppm in the 2 liter Miss Silvia tank.
Flavors seem rounder and fuller. Nice.

Pictures of this cabonator cap?..Ive been thinking of building one. I have seen some really basic designs.

Sean,
The carbonator cap:

It hooks up to this coming from the co2 tank
