I'll agree with MAtthew but also make an added suggestion.  If you take it
step by step slowly it is less pain full on your pocket book.  Step one would
be the basic CO2 running constantly.  Step two might be adding the timer
and solenoid to shut it off at night or when your lights are off.  Step three
would be hook it up with the pH controller.
