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.
