of using this type of reactor is that if you pull some water into the
glass, you get a bubble counter built into the unit.

I noticed that; at first I was upset that I'd let water in, and then realized it had

that at night the CO2 comes out much slower.  I don't see much of a pH

This I have not noticed.  But, I am using bottled CO2 (compressed gas) and you may
be using yeast?  The pollen glass I have would have no way of controlling the amount
of CO2 in the water.  I don't use a controller.  I have it set so that the pH stays around
6.7 all the time, simply by controlling the rate of CO2 influx (which stays the same
day and night).

Wade S. emailed me to say that there is something called Tygon tubing (available
thru the Fisher Scientific Catalog) which does not leak as much CO2 as silicone
tubing and it comes in clear.
