so i got my original regulator back on friday. just now had time to test things out. once again i got everything hooked up and this time (so far...knock on simulated wood) it's all pretty much working with one exception. i'm still having issues with one particular bubble counter.
other than that, i have c02 currently going to five tanks. I'll leave it running for the most part of the day and see where we are at later this eve. If all is still well, i'll hook up the timer and be good.
I'll play around just a bit more with the trouble BC and see if I can't get it leak free.
