Frankly, I've read the manual, but I don't get it!
What I'm trying to accomplish is this:
pH1 is measuring the pH in my calcium reactor
pH2 is measuring tank pH
I'm using pH1 to control the co2 output, keeping pH at 6.8 in the reactor, but I want the co2 to be turned off, no matter what pH1 says, when pH2 goes below 8.1.
I have the feeling that programmable logic might be the answer, but I need someone to tell me the setting I would need step by step!
Is anyone out there who can help me out, please?
