So I am setting up my calcium reactor and have a pH controller to regulate the solenoid. However, it seems to me that there are 2 pH measurements that need to be considered. One would be the effluent pH and the other would be the tank's pH.
I understand that the effluent pH needs to be monitored to ensure that the pH in the reactor remains within a stable range, but isn't the tank pH the "more important" measurement?
That is, if you only have a pH controller on the effluent, even if the effluent pH remains around 6.5, outside factors could continue to depress the actual tank's pH (e.g., excess CO2 in the home, etc...), and the regulator won't close the solenoid, compounding the problem.
I guess this is a long way of asking which pH measurement is more important for regulating the reactor solenoid.
