Just curious as to why you have the needle valve before the solenoid...most people have it the other way around.

Also, I used the exact same metering valve and was able to get it down to 1 bubble per 3-4 seconds.

I do not believe that particular metering valve was designed to be closed completely either, so if you did, it may have damaged it.
