From what i have put together, I can get a PH monitor/controller. Then set the PH I want my tank at and the controller will power a solenoid on the Co2 regulator to allow the flow of Co2 through a bubble counter. This would only be able to lower Ph from what I understand. But aireation (sp) raises PH by displacing the Co2. It seems like it might work but I don't want to invest in something I am unsure about. Only considering it because to keep rays I need to be at 6.25PH and currently my tank is running at 8.0.
