Okay. Two questions for a complete Noob.
1) How do I use a PH Controller to control CO2 injection? I understand the basic principle of regulator, bubble counter, reactor, etc, what I want to know is what should the controller read, ie, if my PH is 8.2 do I want to use the controller to get it to 7.5 or am I just shooting for one specific # such as 7?
2) Can anyone reco a good book on planted aquaria? I plan to only do this once so I want to get it right the 1st time.
