Calcium reactor question

[Ruth]

I just hooked up my new Precision Marine 622 calcium reactor. I think I followed the directions correctly but I did find them a bit confusing. I am a bit nervous as I have never run a CR before and am terrified of crashing my tank as I have heard of other people doing by not having them dialed in correctly.
My question is that I tested the effluent and it is at 7.5. I have the CO2 set at about 60bpm and have the flow out of the reactor dialed back to a slow small interupted stream. Does this sound right to everyone? Anyone have any pointers or suggestions?
