whats up I just set up my co2 injection system and when I tested it I put the hose that comes right out of the gage directly into a cup of water and no bubbles came up. I have the system set to .3cuft/hr and the gage shows that the system is working. Is it not suppose to make bubbles or is there a problem? The system I purchased is the small system from new england hydroponics on ebay.

I assume you plugged in the cord to open the valve? Those are easy to use first make sure you have CO² coming out of the tank. Next strip it back to the output line right out of the regulator.

There is a small LED light that burns with the power is on.

I dont understand exactly what your saying. I def have it plugged in, the tank is open, and it shows on the valve that gas is moving out at .3cuft/hr. I put the hose line for dispersion into a glass of water and no bubbles came out. Shouldnt the hose have enough power to create bubbles of gas in the cup?

Yes it should and you should hear it as well. Try turning it up to see if that works. 0.3 is not 3.0

I put my ear up to it an messed with the control valve turning it up and down and def felt the pressure. I really dont know why it doesnt make bubbles cause I can feel the gas coming out on my finger.
