Just got my Azoos today from drsfostersmith.com. Thankfully I had previous experience with using my Milwaukee Regulator and didn't have to rely on the directions that are written in ONLY chinese. :rolleyes:


Azoo CO2 Regulator

Basically a plug and play module. It comes with two washers for attaching the regulator to the cylinder, and it's a pretty solid construction.

It's got a great performance so far. So far so good with the bubble count. Easy to use and set. We'll see how it does with the bubble count after putting the system on a timer. I'll update in a few more days regarding that.

I guess folks were right about the ease of this regulator compared to others. But don't get me wrong I like my Milwaukee too, but the Azoo was easier to setup to begin with.

I have one to and have been pleased with it over all :) Like you mentioned keep an eye on that bubble count though. when i first set mine up the bubble count would steadly decres each day after the valve shut off at night, when it came back on in the morning it was putting out much lower levels of CO2. I had to end up turning up the working pressure to around 25 psi.... thats what i think its at now..... to get consistant gas release from day to day.

But once the pressure was up, its worked great for me :)

I've got two and no problems (knocking on wood). It's made by Ronco; I'd swear it. Set it and forget it. Well, almost. I've had them for four months now and I've had to fiddle with the needle valve only a few times.

I've got mine connected to the Milwaukee controller so I really don't have to worry about it. Before I got the controller I found myself getting up in the middle of the night checking pH. I'd check it in the mornings and afternoon too. That's way to much worry. I like having these controllers with it. That's the way to go IMO.

But, when I first got them; I knew my starting bubble rate because I was using the same diffuser. I found that they held pretty steady and my worries were basically unfounded. It's a really great unit!

PS: My first one came from Aquatic Eco Systems and the directions were in English. My second one came from the Drs and like you said, the directions were in Chinese. That's a little weird don't you think?

The reason I don't like it is that you can't adjust the working pressure.

Actually the working pressure can be adjusted. Though it says not to, and that it comes with a "pre-set" working pressure, I found that to be WAY to low for me and got a considerably lower release of CO2 the next day after the valve shut off and came back on. I was able to fix this by raising the working pressure up to around 25 PSI..... might just be my imangation but when I turn that nut in the middle of the regulator, it adjust the working pressure ;) Now my Azoo works great, I like it very much and would buy another one any time

Just a quick update. It's been a week or so since I installed my azoo. Works Great! No problems with adjusting the bubble count. No leaks, no solenoid problems and no gauge issues.

I recommend this regulator for its ease in setting up. Screw it on the cylinder, plug it in and it's good to go. My milwaukee took some more fiddling, but works great also.

I have a very silly question. I just got this same regulator, and this is my first CO2 experience. I tried yeast for about 2 weeks before I got frustrated and bought this regulator on sale from the Drs. So I have the Chinese directions that don't help me much. My question is this - do you need to use both washers or are they giving you an extra one?

Thanks,
Chris

Only use one washer...hehe..;)

The other one is an extra one. After you use that second one ask your CO2 supplier for extra washers. You replace the plastic washer after every cylinder refill. Using two washers at once is asking for leaking issues.

I have had one running for about 4 months now with absolutely no problems and with the default working pressure. I had a poc Milwaukee and could never get that one to work properly no matter what I set the working pressure to. The Azoo is a really nice regulator.

The regulator is a solid unit. I really like mine.
But I would ditch the soft plastic washers that come with it. Home brew supply places have hard nylon regulator washer that are way better - they won't get squished and get stuck in the thread as those plastic washers would.

What size airline tubing?

Just got my Azoo regulator a few days ago as part of the Drs. Foster & Smith package (bubble counter, airline tubing, etc.). The problem is that the airline tubing appears to be too big to fit the regulator--it looks like 6mm. Everytime I try to attach it, I can easily pull it right off again, even after tightening the nut.

Do I need 4mm? Does anyone know what size Azoo takes? I will likely have to order new tubing online if that's the case, since all we've got around here is crappy Petsmart.

Also, my psi is up at 50. Should I adjust that down to 30? I tried turning the center bolt but didn't see it change, really. I am so NOT mechanically inclined and always afraid I'll break something!

Odd that you're having problems with the tubing. Is it the blue silicon stuff? I would switch over to CO2 proof tubing if you can.

I will add though that when I bought the semi-auto system from Dr.F&S, the check valve included did not do a very good job. The solenoid got screwed but I opened it up and polished it. It works fine now and I am still very satisfied.

Yeah, I finally figured it out--I had to unscrew the nut all the way, cut a short piece of tubing, fit it over the connector, jam the other end through the nut, thread the tubing through, and then tighten it down. Every other piece of equipment I've used has worked differently (pop the tubing on and screw it down) so it just took me a while to figure it out!

I got problems with my new Azoo regulator. The bubble count reduces over time no matter what the output pressure is set. I tried 20 up to 40psi and after a few hours, the bubble rate drops from 2bps to less than 1bps. Also, the output gauge can't keep a constant pressure. The needle on the output gauge bounces up and down around the set value. I checked everything for leaks but couldn't find any. I notice that when I open the needle valve widely, the pressure is constant but to much CO2 output. As soon as I dial it down, I get inconsistent bubble rate and the needle moves again. Do I have a bad needle valve? Any suggestions?

I am having the same problem. I have it set at 30psi and it's very inconsistent. It's only day three using it though, so I was hoping I just needed to keep playing with it...but now I'm not so sure.

I have been playing with it for a whole week. I spent almost an hour everyday trying every way I could think of. Actually I thought I got it once. I had the output pressure at 38psi and 2bps. It was very stable for 2 days. And then it dropped. It was really frustrating :mad: . I'm thinking of buy a new needle valve.

I'm still having the pressure drop problem. Even if I set the bubble count at up to 3bps, it will drop to almost nothing (or nothing) by the end of the day. It's very frustrating. I have it set at 30psi, and I've tried all the way up to 40psi with the same problem. Right now neither of my regulators is working properly!! :mad:
