Reef Octopus CR 200

[FLReefer101]

I just bought a new reef octopus cr200 and need to hook up another ph probe to my apex fusion. I only have one port which has my ph probe for my aquarium but need to add one for my calcium reactor. Can any one point me in the right direction. I already have a new ph probe so what else will I need?

So I need a pm1 module, answered my own question.

Which model of Apex do you own? The full Apex (2016) has an ORP port which can be used with a 2nd pH probe instead of the ORP probe. Otherwise, as you mentioned, you'd need the PM1 module.

See my Apex Hardware Overview article for all the available modules:
