Kalk reactor help

[gotfish8]

I was wondering if some could help me out?

I currently have a MTC procal reactor and decided to add a GEO kalk reactor for PH stabilization.

This is what I want to do. Can I draw in water from the tank/saltwater via a dosing pump and run tank water thru the kalk reactor instead using RO/DI top off water?

I am just dripping kalk now but I have very little evaporation so I am overflowing the sump to keep my PH up


Can I run the dosing pump on a AC3 to only turn on when PH is below 8.2 and off when above 8.3

Thanks for your help

The kalk reactor will have to be run with RO/DI, the kalk does not mix well with sw.
