Re: more CO2 regulators

Looks like I need to proof-read my posts.
Here's what I meant to say:

I couldn't disagree more.   A properly adjusted "open loop" CO2 system can
result in a very stable pH, and is VERY reliable.   Using a regulator, needle
valve, and simple reactor, with no solenoid, I get just a .2 pH swing, 
verified by an electronic pH meter.   And my KH is only 3 degrees.

Yeast bottles are a whole different matter, due to the varying production
of the yeast mix.   It would be like having someone continuously adjust
the output pressure of your regulator.
