To start the yeast read the yeast lable for the particular type you are
using. It will be either 85 degrees for the cake yeast or 100 ~ 105 degrees
for the fleischmans and star bread yeast. I used to start my suger/ warm
water mix and let it sit for a day. You will see foaming at the surface and
that means the yeast is alive and kicking! Then just hook it up to your CO2
reactor.
Now if your yeast bottle is in a very cold area you may have difficulty
keeping the yeast culture alive. Mine was in a room that didn't get below
65 degrees at night (winter) and during the day it would sometimes ballon
into the upper 80s (summer). I kept the yeast bottle on top of my aquarium
hood in order to help it heat up when the lights kicked on.
Also as far as the baking soda goes... it's fine to add it to counteract the
soft water conditions mentioned in Dacaprice's post.

Also check for excessive heat as this will kill the yeast

Ok.... so far everything I have read about a DIY CO2 setup is very
similar. I opted to by the Nutrafin system... but with the packets
they sold me I was getting nothing. I think the yeast was dead.
Regardless, I re-made my own mixture with yeast and baking soda using
the same measurements that come in the packets. I finally got
bubbles, but they only lasted a couple hours then nothing. I then
removed the Nutrafin canister and used a 1 gallon juice bottle,
increased the amounts of everything and presto... great bubbles. But
again it only lasted a couple hours. What is going on!?!?!? It is
very frustrating. I have soft water here; we have a water softener in
our home. Does that make a difference? Should I try a different
brand of yeast? Right now I am using Red Start Active dry yeast which
was just what was at the local supermarket. Any help would be greatly
appreciated.
