Questions for those running Calcium Reactors:

1.) Do you use a controller?
2.) If so, which one? (in particular - what about the Pinpoint PH controller)
3.) Thoughts on using one?
4.) I have an AC JR. but from reading don't think I can use it to control the reactor even though it says it can serve as a controller. Maybe I just haven't figured out how to set it up.

Thanks reef nuts for help!!
