Sound advice. Note also that aluminum tanks are much
lighter than steel.

I beg to differ. It's probably the least necessary part of
the CO2 system. It only provides an erstatz value for the
CO2 in the water which is what one really wants to contorl.
Much better method is to use a pH and a KH test kits and
the pH/KH/CO2 table.

But it won't tell you what you really ant to know, i.e. the
amount of CO2 in the water. for that, see comment above.
Perhaps by "regulator" here you mean pH controller and
solenoid? I would agree that a pH controller and solenoid
are luxuries and nto at all necesary. The pH will be pretty
much as stable without a controller as with one.
