marine monsters needle valve


I was looking at the needle valve on the Marine Depot website (aka marine monsters) and the info states that it can provide down to 10 bubbles of CO2/minute at 0 pressure. Is this the Clippard needle valve that people are recommending? It looks right in the photo, but the 10 bubbles per minute is confusing me. Aren't we trying for bubbles per second and why would you have any bubbles at 0 pressure? Sorry if these are stupid questions -- I'm on CO2 info overload.

Down to 6 bubbles per minute... they are just telling you how great a piece of equipment that is. Of course you can open it up and bubble more through it, 20, 60, 120 bubbles per minute, whatever is desired. The trick with needle valves is to get them to bubble a low number of bubbles without closing up completely.

I didn't see the "at 0 pressure" remark... you are right, obviously this doesn't make sense!
