Hi Heather, Wow, when you said "chinese" regulator, I assumed you meant something akin to the Milwaukee or JBJ. But that would truly be a chinese regulator language and all. From the pictures, I would have to say you have a non-adjustable regulator, but that really is just a guess. Still you should be able to dial back the bubble rate with the needle valve without worry about blowing it out. That being said, the LFS that sold you the system has an obligation to you as a customer to support what he sells so I would not recommend doing anything other than dialing down the needle valve prior to contacting him for your next steps. I'm sure he'll be more than happy to help you set it up or get something that will work for you in exchange.

The image of the side of the regulator isn't very visible, but there is what appears to be a slot for a screwdriver to go into. Thank you very much, Troy! If it is adjustable, I will certainly use your directions. I went and looked at glass gardens, my pH meter is the same 122 you show there. And frankly, your Milwaukee regulator is cheaper than what I bought before. I do want to order some CO2 resistant tubing from you anyway--will have to see about taking this regulator back.
