CO2 problem

[Ruth]

I'm thinking the same as Kari. I monitor PH pretty closely although the CR does have an extra de-gassing chamber so I may not notice a faulty regulator that way.
I really like calcium reactors for what they do to my tank stability but I hate when stuff like this happens because #1 I am an idiot at trying to figure stuff like this out and #2 pressurized gas scares me!
