You should only adjust the working pressure when the gas is on, you may be doing this already but worth mentioning. It's normal for the atomisers to fill a bit with water. Mine used to get about 1/3 to 1/2 full, then when the gas came on it would push some of the water back through the ceramic...

not sure, still haven't had time to check... a job for next weekend.

I've just updated my journal... I tested the atomiser for leaks with soapy water, couldn't see any leaks so I put the CO2 on for the next day so I could test it in water when I got home from work. Guess what I found. An empty CO2 bottle :facepalm: so wherever the leak is coming from it seems...

Cheers Nath, I'll test in water at the weekend and see if it's leaky or not. Those metal clips may be the way to go.

Right, I just tried the soapy water trick, can't see anything but it's difficult to see all parts of the atomiser inside the cabinet. I'll have to try to submerse the atomiser when it's on to see if there's a leak. One question about that... If the atomizer is completely disconnected from the...

I'm going to test the unit tonight. The co2 has been off for a couple of days so I'm waiting for the pressure to build up inside the atomiser. I'll let you know what the result is.

I've been thinking. Could it be possible that when my canisters are filled, the temperature or some other external factor is having an effect on the amount of co2 going in? If that makes sense?

I haven't had a chance to test yet. I'll have a look tuesday night. I think there must be a leak as I've gone through 1kg of co2 in just over 2 weeks and I doubt it ended up in the tank. Mist wasn't as much as when I started and the shrimp are fine. I got an e-mail from Tankscape today saying...

Hi all, I have been using the JBL CO2 kits with 500g refillable canisters on my tank (journal in my sig.) I have been going through canisters pretty quick, especially the last couple of weeks. I investigated and can hear a clear hissing noise coming from my UP inline Atomizer. I've changed...

I've put it on 2.8 for now, I've still had to open the needle valve quite a lot to get a steady 1-2 bubbles a second. I'll see how things are tomorrow, this is something I'll monitor closely and make adjustments if need be. Thanks for all the help :thumbup: Cheers Dan

Yep, it's working. Thanks for all the help guys. The only thing now is how should I set it, does it make a difference? Hogan has it at 2 but Ian has his at 3. I'm not really sure what to set it to. Is there any way to judge or does it not matter as long as there's gas going through? Cheers

Also would I be right in assuming I want to turn the screw clockwise to increase pressure?

HAHA I'm such a Kev. I thought all the stuff I'd read online was referring to the plastic lug ON TOP of the reg. I've found it now. Can't believe that :oops: How slowly are we talking Ian? Also how far should I open the needle valve before I start adjusting the pressure?

Thanks for all the replies. I've tried to adjust the working pressure but can't get the needle up to 2 bar. It sits around 1.7-1.8. The canister is newly filled as well so it's not that it's running out of gas. I can see a slight mist of bubbles in the water but it isn't as much as I think it...

Hi all, Set up my new Natural Aquario set up yesterday (Journal begins soon), all is done apart from the CO2. My question is really two: 1. I have the reg that has a screw to adjust the working pressure on a 500g cylinder. The needle showing working pressure has been sat at just under 2 bar...

Hi Guys, I was wondering if anyone here uses, or knows if you can use, an atomizer like a UP with a JLB CO2 kit. The kit I have is the JLB M602, and I'm not sure if the pressure is high enough to use one of the UP inline atomizers. The instructions say they can put out up to 6bar, but I doubt...

Yeah I've used their glass diffusers, they seemed to work well and look nice. I've heard plenty of good things about their regs and other bits too.
