Apex and calcium reactor

[natgun1]

well I bit the bullet and bought a calcium reactor and all the bells and whistles to go with it, but as I sit here putting it together im not sure if I need a pm1 module for my apex to control the ph or can I plug it into my ph/orp port? any help would be greatly appreciated thanks.

You can switch the pH2/ORP port to pH mode and use that for the CaRx. If you are using an ORP probe and don't want to give it up, then you'll need to add a PM1.

Great to know as I in the future will be running a calcium reactor and will not be running orp. Thanks!
