Reefkeeper PH probe ??

[savage]

Hey all
I was think of purchasing reefkeeper controller with my calcium reactor I need two PH probes to monitor the PH in the reactor and the tank so my question is do I need to purchase any additional hardware other there the 2 PH probes??

Thank for the inform... I'm feeding the reactor form my return line I also have a regulator with a selenoid plugin and of course the circulation pump which one is used to shut off the reactor once it reaches a PH of 8.3??
