feed pump for kalk stirrer

[james1990]

I'm picking up a 2nd hand Precision Marine Kalk reactor and was wondering what pump to feed it with.

I know the reactor is fed by RODI and not tank water, so is an expensive dosing pump or submersible pump needed? or do I run a cheap aqua lifter from a RODI tank into the kalk reactor? just not sure how it works.

thanks all
