Need Help KORALLIN Cal Reactor/PH controller

[boxer385]

just purchase a used kprallin in excellent condition, what i noticed
it doesn't appears to have a place for a ph controller to monitor
it inside of the reactor? So what do i do now.

i do have a neptune controller for my tank with ph probe

I bought the same one without the port for the PH probe. They make one, but it's pricy. I bought this PH port fitting and put it on mine. Works great.
