I am planning to build a diy calcium reactor out of an old media reactor I have laying around. I think i have the concept of the reactor itself down pretty well. I'm not sure I fully understand the co2 regulator side of things.
I understand the need for a regulator to control the amount of co2 going into the reactor. Im assuming this is what will determine the ph of the reactor. I plan to use a ph probe and my apex to control the reactor.
My thinking is I can regulate pressure/flow to a slightly lower ph than what I am after, and use a solenoid to open and close the flow of co2 in order to fine tune the ph. For instance, set the reactor to a ph of around 6.9, then use the solenoid to keep it closer to 7.0. Is this pheasable? Do I really need a flow meter/metering valve and a bubble counter?
Then its just a matter of pushing tank water through the reactor at a rate that meets the tanks alk/ca demands, correct?
Also, I'm assuming I can use a set flow rate on the effluent pump, and adjust alk/ca by raising or lowering ph?
