CA reactor or Dosing?

[GMGQ]

Great feedback everyone, thanks so much.

I think my main issue could be the CO2 regulator/solenoid.

I've been reading about this new Digital CO2 regulator. No more mechanical needle valves/bubble counters -- this one is all digital/electronic. You turn a dial to set the # of bubbles, and that's it. $170. They'll even install it on your existing regulator for you for free (you just gotta ship it to them).

So that's another option... Hmm....

Well my reactor setup has been running steady the past 3 days. I'll just keep an eye on it and 'make do' with it for now. But I'm glad there has been some good discussion on this topic, as it's good to know for the next setup (or if I get fed up with this one!).

Thanks again everyone!
