Darkblade48 Glad we could be of assistance

trixylarue Well I finally got it working. It seems there was a leak in the check valve. I stuck in under water and it was bubbling. I took it off and now everything is working properly. Now I just got to buy a new one and I should be set. Thanks for your help everyone!

oldpunk78 Can you take a photo of the low pressure gauge?

trixylarue Here is an update on my CO2 woes: I still cannot figure out how to make this thing work. I used dish soap and found a leak at the top of the bubble counter. I took off the top and screwed it back on and it seems to have fixed it. I still have the pressure at 30, there are bubbles coming out of the tube at about 1 per second (the bubble counter is currently set at 3 per second until I get this thing working). but still nothing will come out of a diffuser and I tried two different types. I am completely clueless.

trixylarue I received an e-mail from Green Leaf and they said the same thing. I shut it all down and I will take it all apart and start over again tomorrow to see if that fixes it. Thanks for your help!

My apologies, I only skimmed through the last page.

If your regulator is set at 30 PSI delivery pressure (and assuming your needle valve is open wide), and your tubing is only bubbling very slowly into the aquarium, I would look for a leak. Even at 10 PSI, my tubing will bubble very quickly.

Darkblade48 If you want to eliminate the possibility that it is a faulty diffuser, simply take the diffuser out and have the airline tubing bubble directly into the aquarium.

trixylarue Still no gas in the tank. All it seemed to be doing it sucking water back up through the tube. I am trying another cheap diffuser just to see if that is the problem...waiting for pressure to build....sooo wanting to see bubbles in the tank!

TheKribKeeper Could be a bad check valve some need high psi to open referred to as cracking pressure. Or it is stuck closed. But you did right by trying a cheap plastic one now you know the problem lies with the check valve or the diffuser.

trixylarue Ok - there were bubbles coming out of the end of the tube. I replaced the brass check value with a cheap plastic one I had - we'll see if this works. By the way - I cannot blow through that check value - I should be able to right? Perhaps it is a bad valve?

TheKribKeeper Also if you have an inline check valve after the bubble counter try it without that installed that could be faulty.

1. Just bubble counter connected you get bubbles-The bubble counter is good.

2. Connect hose put open end in water if you get bubbles-hose is good and not clogged.

3. Connect check valve on just one end put other end in the water if you get bubbles- check valve is good.

4. Connect diffuser put in the water if no bubbles after an hour then the diffuser is bad or needs too much psi to operate.

5. This is the process of elimination.

TheKribKeeper Is the bubble counter bubbling when you turn the co2 on? If it is then connect just the hose and put the hose end in the water if you get bubbles out of hose then all is well. Then connect the diffuser to it and wait 30-60 minutes for it to start working if still nothing you got a bad diffuser or it needs extremely high working pressure which is sketchy past 50psi. That is all it can be you have isolated everything else.

trixylarue I took the top off the bubble counter and it is all clear. Not sure how to check the check value at the bottom of it. The reason I decided to spend $375 on this regulator is because I didn't want the challenge of having to buy everything separately and put it together myself. Not thinking I got my money's worth now. LOL.

TheKribKeeper If you get no bubbles at all then it is the needle valve or regulator. Unscrew the bubble counter cap where you fill it with water and see if you can blow through it if not something is clogging it the check valve is in the bottom of the bubble counter where it screws on the needle valve not the top so you should be able to blow through it if not it is clogged.
