Is there a way to use the RA as a ph controller for the deltec PF501 calcium reactor?

Yeah i forget the function off hand but its like the heater function.but you set a low and a high ph to control your solenoid relay.

Someone correct me if I'm wrong, but I think it might be: Or

so basically use one of the ports and switch on/off the power to the solenoid while reaching a certain ph range?
that being said, I would lose the ph monitoring of the main tank if I deploy the ph probe into monitoring the reactor.

You could always get a PH expansion module. Then you could have both

I already have a salinity expansion, so if I were to add another ph expansion meant I would have to get the expansion hub also, am I correct?

Yep.

You could also control the solenoid based on the ph of the tank rather than the ph of the effluent. At least till you get the hub and expansion.

many thanks guys
