Need help ASAP with CO2 set up

Yesterday everything was fine with my CO2 set up. But tonight I came home to a big problem. My tank is at 44 psi and my bubbles are now flowing out of control it seems. It's like the needle valve isn't even working. And there's this weird fuzzy bubble layer in my bubble counter.

Oddly the fish don't seem to be affected by the CO2 level, and the bubble diffuser doesn't seem to be working. It's like no CO2 is coming out. Help please!

if your tank pressure is at 44 psi, your are probably out of CO2 and if you have a single stage regulator, i have heard of people gassign their fish since once all the liquid CO2 has converted to gas, it rushes out very quickly. Can you please shed more information on teh CO2 setup. How old is it, new co2 tank. etc.

No sorry the tank is at 1000, the second stage is 44. Tank is still full.

Bought it used off a great member here, I think only 8 months old?

ok then its probably the needle valve. can you adjus tthe needle valve at all or does it seem like the needle valve is not doing anything. I had this happen to me when my handle came off and you just need to attach the handle back on. You will know if the knob is very loose if this is the case.

Well I have a Parker meeter valve (I believe). How do I attach the handle that you're referring to?

And it seems like this should still be bursting out the diffuser no?

It's not for some reason?

Do you have a pic of the regulator?

What would Honey Badger do?

Here ya go!

And I can confirm co2 is indeed coming out of the tubing. I'm able to lose the needle valve if needed, right now it's very low

OK - so let me see if I have a clear picture of what's happening.

Yesterday, everything was running good.What psi was it set at?

Today, you come home to find that the working pressure has risen to 44psi. Have you tried putting it back?

What type of diffuser you using? Have you checked the line and reg for leaks?

Also, keep in mind that those aren't the best regulators out there and are prone to a little mishap every now and then.

Also, you say you can't adjust the bubble rate? Please explain how you are adjusting it.

The psi has been at 44 since I've had it pretty much. And on the black valve seen in the photo my setting was at like 2 (bigger tuning) - 5 (fine tuning).

The bubbles have been going at about 1 bubble per second.

Today I came back and the bubbles were going crazy in my bubble counter and now I've turned it down past 0. it's now at -14 (big) - 3 (fine) in order to keep the bubbles low. Now theres just no bubbles coming out of the diffuser which is the Archaea one from AFA : http://www.adana-usa.com/index.php?m...roducts_id=489

No idea what happened since last night?

You have a leak somewhere or a clogged diffuser. Test every connection everywhere with soapy water and watch for bubbles.

What would Honey Badger do?

Will do. Any ideas if there aren't any?

No leaks with the soapy water test... I'm so stumped.

I've only had the ceramic diffuser a couple weeks so I doubt it's clogged.

Any other ideas?

Should I try taking it apart and reattaching?

Need help ASAP with CO2 set up

Sounds like a blockage that has been dislodged to me. I have a dual stage regulator my tank always reads about 700 psi when full and I have the output at about 12 psi then fine tune with my needle valve. My tank system is 155 gallons. I honestly haven't heard of using that high of an output from the regulator. My fish would all be dead and my plants melting but thats my setup. i also use a reactor. Most needle valves can only handle a certain pressure range. You may want to check the manufacturer specs to see what your model can handle. Then adjust accordingly or replace.
