Air in calcium reactor

[straightrazorguy]

I have the same problem with my Vertex calcium reactor. It started while I was on vacation, after using the reactor with no problems for over 6 months. Since then I tried everything; burping the gas recirc line, messing with the pump, etc. I even contacted the Vertex people and they didn't have a good explanation or suggestion. So, I'll be watching this thread with great interest....
