Topic: Tradition Offerings (2 msgs / 60 lines)
1) From: Dan Bollinger
Hi folks.  It wasn't until last week that I realized I  have something to offer
to you in the homeroast list tradition.
I am offering calcite for treating R.O. and distilled water for coffee brewing.
Calcite brings the pH to neutral and adds a little hardness, too. I'll mail
gratis a pound to the first five people that reply to me offline.  A pound is a
year's supply. I'll include instructions on how to use it.   Dan

I'll send them out in monday's mail.  For everyone else, here is the instructions
I use. I got my 40# of calcite from Grainger's.  That was before I learned that
you can buy calcite cartridges for filters.
I have been adding calcite mineral to my water that I use for making espresso,
coffee and tea.  It makes a good tasting drinking water, too. It's weird drinking
water coming from a pitcher with 'sand' in it! I've named it "pHlavor Grains
(copyright 04)."  Cute, eh?
RO water tests at about 6pH. Adding calcite brings it to 7pH, or neutral. Once
the pH gets to neutral, the calcite stops dissolving. So, that means you just add
a lot of calcite let it neutralize the RO water, and the rest will sit on the
bottom doing nothing. The resulting hardness is 30-40ppm as I recall from my
tests. Since it is easy to do, self-regulating, and makes the water neutral,
which your boiler will appreciate, this is all I do to treat my RO water.
Here's what I do. Get a gallon plastic pitcher with lid. First, you have to rinse
the calcite before you use it the first time. Put a cup of Calcite in it. Fill
the pitcher half full with regular tap water. Shake, and pour off. Repeat.
Now you are ready to use it. Fill the pitcher almost full with RO water. Turn the
pitcher upside down and back so the Calcite grains have a chance to tumble to the
other end. Repeat 5-6 times. It works that fast according to my tests. Let the
calcite settle. At this point the water is fully treated. You can leave it set
overnight and nothing will happen. The cloudiness (half is calcite fines, half is
gas being released) will diminish in a few seconds. Then, pour over your espresso
machine. A cup of calcite will treat a year's worth of water.
