Seems like all ceramic/glass diffusers work the same whether it is a $50.00 ada one or a $1.99 Chinese one. Most come from China anyways so....

Yeah sometime you do get what you pay for. However, I agree with you Mantis... I see a bunch of people happy with AquaticMagic lily pipes. I have Cal Aqua pipes, but I do have an Up Aqua diffuser and a no-brand glass drop checker from Ebay... all work great! This NAG music note diffuser is $16. Beats spending close to $50 if it does the same thing... we'll see.. I just ordered one!

looking at the same item...

I wonder if this works for a yeast DIY CO2 generator. I got a small diffuser from eBay but it produces only one stream of CO2 bubbles. On the other hand, Fluval's diffuser for the 88g set produces at least 3 or 4 streams of much finer bubbles. However, glass diffusers look much more elegant in the tanks!

I disagree. All ceramic/glass diffusers work in the same manner, but the quality and quantity of the CO2 dispersion is VERY dependent upon the quality of the ceramic disk. I've used cheap ceramic diffusers and ADA ceramic diffusers and there is a big difference in their performance. The cheap ceramic diffuser did not produce as many CO2 bubbles and the bubbles it did produce were much larger in size. Also, this was for the ceramic diffusers coming straight out of the box so cleanliness should not have been a factor - I've noticed the efficiency of the CO2 dispersion to be very dependent upon how clean the ceramic surface is as well (which is why i go to great lengths to clean and maintain my CO2 diffusers).

I agree with JeffyFunk on the different qualities of different ceramic disks. I wonder if the NAG diffuser works fine with DIY CO2 generators.

Well I placed the order and I'll receive it sometime next month. I have a pressurized and DIY system so I'll let you know if it works it both. I'll also comment on the size of the bubbles it releases.

I haven't had that many diffusers, 3 so far. My cheap Up-Aqua glass ceramic diffuser does have larger and small bubbles coming from it -- I also go to great lengths to clean the diffuser plate in H202 every time I do a PWC. I'm a bit disatisfied with that, but it works; my drop checker can attest to that. On the other hand, my black Fluval ceramic diffusers was even cheaper but the two that I have both create a fine mist of co2, better than the UP-Aqua. I'm sure that the ADA and Do!Aquas are the best, I don't dispute that... I just don't feel like spending that kind of money since I'm a full-time student. And then there's atomic GLA diffusers, those ae suppose to be great too... Anyway, we'll see how this NAG one is when I get it. Pretty good deal for $16 bucks shipped -- unless it's a total POS? LOL

Here's the one I actually ordered (shorter version from the pic I posted earlier)... hope to use it in an ADA 60-F I just ordered. :)

hope that NAG does quality control

My eBay glass diffuser is still working - giving one stream of CO2 bubbles. (5 days have passed)

But my Fluval diffuser for 88g kit stopped producing bubble after 4 days although it used to give finer mist of CO2.

Both bottle are the same size (750ml) with the same formula.

Anyway, I hope that NAG's diffusers have a uniform quality. I hope not that only some lucky ones work fine.

ADA and Do!Aqua produce very fine and consistent bubbles I have seen to date for a long time. Even Barr recommends if you go disc diffuser go ADA.

You could check for used ones, they pop up from time to time. And probably by the time and money you spend trying all the knock offs you could have bought a genuine pollen glass.

Alright as promised... AN UPDATE!

Okay this NAG-Aqua wasn't suppose to arrive till the end of April! I got it early, so no complaints here!

It was ordered on March 11th and I received it today :)

Let me tell you, the quality on this little diffuser is superb. I wouldn't be surprised that it's from the OEM manufacturer who produces ADA/Do!Aqua stuff! Not only did I save money, and I GOT MORE THAN WHAT I PAID FOR (in response to the old adage of "you get what you pay for"), this little gem produces some pretty small bubbles with no sign of co2 leakage escaping between the ceramic plate and glass -- something which unfortunately happens in my UP Aqua diffuser. I can't comment on whether or not they're production process produces consistency in quality in their other NAG diffusers... good news is, I ordered another one to report on that! :)

hmm i was just about to order the rhinox diffuser but saw this one too.
what's your co2 setup? is it a fixed output or adjustable? what's the outward pressure you have it at?

I'm not going to say they are all the same, but many of the pricier ones are the same ones being sold on ebay for much less from vendors like aquatic magic. Same goes for some of the LED lights, etc. They are just re-branded. I've had a Rhinox for over 5 years and still producing that fine mist.

I believe I have the same fixed output regulator as you right? the Azoo one?

Which co2 regulator are you using the rhinox on?

Granted, nothing is really wrong with Rhinox. It just depends on the style of diffuser you prefer. ;)

As far as the comment about "cheap" ceramic discs go, I've had more and finer bubbles come from cheap eBay diffusers (the up-aqua ones) than I've had come from a brand new $140 ADA Pollen Glass Mini. I think each ceramic disc is a bit of a hit and miss situation, but that's just my personal opinion.

I'm using an Aquatek mini regulator for paintball. I believe the fixed output pressure is 30 to 40 psi.
