Milwaukee Controller Help

[jefft321]

Hi, I just hooked up a Milwaukee pH controller to my Calcium Reactor and I was wondering what the best way to set it up was? I didn't realized it doesn't have a high and low shut-off, or does it? It looks like it's just a low point. I have large grade (looks like broken up coral pieces), ARM media. What do I set the low point to? I guess it doesn't need a high point setting since the pH will never get that high in the reactor.
Thanks, Jeff

I have mine set aroung 6.5-6.7 but would be interested where others have theirs set.
