Perhaps I am missing something, but I saw nothing about pH controllers on
the link you provided. I am all set as far as regulators, needle valves etc.
are concerned.
I am looking for information about pH controllers which will drive a
solenoid to turn the C02 stream on and off as needed to maintain a stable
given pH (which in my case will be about 7.0, which will provide me with
optimal C02 concentration).

1) How long can I expect my 5 lb CO2 cylinder to last at a rate of about
1
bubble/sec, 24 hrs/day.
As of today its 5 months. I dont see any pressure change and hope for one
more month. Mine 2 bubble/sec
2) What are people's favorite brands/sources for controllers.

3) Is there an inexpensive but reliable controller out there that I
should
consider?
See the link above.
4) Are the solenoids reliable, or are they failure prone?
I dont use any.
5) How much of a hassle is controller calibration, and how often do you
have to do it? Are some easier to calibrate/maintain than others?
NONE.
