  • Produces Small CO2 Bubbles
  • Made of Break-Resistant Acrylic
  • Easy to Install

This CO2 diffuser from Aquario is one of the best on the market. It features a small, brown ceramic disk which does an excellent job of breaking down CO2 gas into the finest mist of bubbles. The finer the bubbles, the better the CO2 can dissolve in the water and therefore plants have an easier time utilizing the CO2.

The other great part about this diffuser is that it's made out of break-resistant acrylic as opposed to glass so it can very easily be attached to tubing without having to worry about smashing it. Suction cup is included for easy installation. We've found the large size diffuser to work in any aquarium and as such, we only carry the one size. Co2 pressurized gas system required to utilize this product.

Nice fine bubbles

Nice clean looking design, secure suction cups, and produces a fine stream of bubbles.

Works awesome

So I have this on my 5 gallon tank running about 1 bubble every 1.5-2 seconds and it will make super fine bubbles. The amount of growth I’ve gotten is well worth the investment into co2. The only issue I had was I don’t think I had the airline pushed far enough down and on day 2 it popped off but since then no issues.

Great all around diffuser for the price.

This is my first diffuser , I’m currently using it in a 20g long . For a budget diffuser it’s getting the job done fine. I will be upgrading to an atomic diffuser soon but that’s only because this tank is pretty shallow and I think I will be able to reduce my bubble rate with an even more efficient (but way more expensive) piece.

Works with DIY CO2

Even though it's advertised as working only with pressurized CO2, I decided to take a risk and see if it would work with a DIY yeast system. I'm using the design from MJ Aquascaping. To my surprise, it's working very well! I'm here to buy 2 more for my other tanks.

Perfect

I use the fluval diffuser first and this one looks much nice and more bubbles are made and are smaller. It’s also easy to set straight since it’s tall. MAKE SURE TO USE CO2 AIR LINES, they are more rigid.

Aquarium Co op is great!

4 star review. not 5 because initially the connection between the tubing and diffuser leaked nearly all the co2. I acknowledge this may be more of a problem with the tubing and not the diffuser however I am using the tubing sold from aquarium co op. I solved the leak problem by shoving the suction cup holder on the diffuser over the air tubing line on the connection (see picture). Now it works great with no leak. Aquarium co op is a great company with great products. However, one area for improvement may be air lines and check valves for co2 equipment.

Works great

Does exactly what I think it should - diffuse co2.

Super cool!

Gonna be honest, I didn’t mean to order this. I don’t have any high tech tanks because I’m still new and I’m not quite ready to tackle CO2 inj. But it’s really cool regardless!

This was my 1st diffuser

My first one was destroyed by a faulty co2 regulator. I replaced it with another brand from my lfs. Was not good. I ordered another of this one. Everything is perfect again!

Excellent tiny bubbles

I am very happy with the way I get a mist of bubbles from this diffuser. I have 2 and would buy another if they were in stock!

Excellent, but stopped working.

Fantastic diffuser, but the air stone stopped letting aid through it. Have to buy another one.

Very nice diffuser

Diffuser is working wonderfully, bubbles so fine that it almost looks like smoke. Dual suction cups are very nice and secure. Instructions are a bit lacking, but you may want to fill the bowl with water to count bubbles - this will need an oral syringe and short piece of air line tubing to do as it requires some pressure and the pipe is quite narrow. This can also be used to help clean the diffuser element later. You will need a pressurized CO2 source too of course, less than 10psi doesn't seem to work well.

Aquario Neo CO2 Diffuser

This being my first time running a CO2 system I must say through research and looking through quite a few options I finally decided on this diffuser. I have a 75 gallon aquarium and running a 20 lb CO2 tank at roughly 4 bps the bubbles are super fine supplying the Perfect amount of CO2 that in just 2 weeks the visible change of my plants have been spectacular my dwarf hair grass is spreading, Amazon swords growing massive and my horn wart( which grows fast anyways) not only grows faster but stays a wonderful green. I would suggest anyone looking into running CO2 to get this diffuser, another quality product from aquarium co-op !!!

Good stuff

Much better than the all glass diffuser which I kept snapping over the years… lets see how it does with algae growth

Perfect!

This may be a little diffuser but man it makes some tiny bubbles that float around a long time in the water. Just make sure you let us soak before booking it up.

Neo Diffuser is problematic

I bought an Aquario Neo CO2 Diffuser from ACO the previous year. It worked fine for months then the top of it came off. ACO replaced it and the new one has been working fine for about 3 months until today.

This time the CO2 is escaping from the edge of the pipe lip and not diffusing through the stone. I am going to attempt to fix this with superglue as others have done. Love the co-op support but not this product.

Wow!

I didn’t know there could be a big difference in defusers and had one by a well known brand but wow was I wrong! The fine bubbles this one makes beats the other one hands down! Been a month and the difference with just changing the diffuser has made a huge difference on plant growth.

Micro fine bubbles and the ACO guarantee

Had an issue with my diffuser after 6 months of flawless perfect operation and Aquarium Co-Op resolved the problem. Great products and even better customer service.
