Neo CO2 Aquarium Diffuser - CO2 Diffuser Aquarium Kit, Fine Mist Oxygen for Fish Tank, CO2 Diffuser for Aquarium Plants, CO2 System for Aquarium -Normal Special Diffuser, Large

The media could not be loaded.  This is a very nice diffuser, very fine bubbles. Love the aesthetics. Just what I was looking for.

I've been through 4-5 diffusers over the past year and almost every one them doesn't work correctly out of the box and/or stops working after a few weeks. I thought something was wrong with my CO2 tank, tubing, check valve, bubble counter, etc. I replaced tubing, check valves, o-rings, tightened everything countless times, tried different CO2 ingredients, but turns out this was the issue. Works beautifully with nice even bubbles coming out all around. Make sure to soak it for a minimum of 10 minutes before use, but so far so good. I also tried all the other diffussers I had after replacing parts and they all had the same problems, so I'm confident this was the issue.

The media could not be loaded.  Video taken 1 minute after CO2 switched on, bubbles already perfect. Love how it looks and how it performs. The tissue culture plants went in about 6 weeks ago and in combo with the light and NilocG Thrive fertilizer, are going crazy!Wish the suction cup was a bit stronger, but honestly can’t remember if the cup is from Aquario, or came with the tubing.

First of all. The product itself is great. One thing I hate, is it is the only thing in my tank that gets algae build up. I know there is no such thing as algae free aquariums. But visibly, I have zero algae. Except this thing!!! It’s the only thing that turns green in my tank. Oh well, I’m leaving it in and it isn’t worth taking out. Product itself is great.

I love this product since it's hard tubing looks perfect in the tank straight downwards , I don't even need to use suction cup since my tank is only about 12" in height. anyways I received it yesterday placed it in warm water for about 3 hours before I installed it. While I was using it yesterday for about 2 hours I notice some bubbles were big and also co2 pressure was weak for a small period of time. Today when my co2 turned on the big bubble problem disappeared the weak pressure problem was still here but only about 10 minutes or so. Other than that it looks absolutely great in the tank and don't have any other problems

This diffuser and joint were terrible. I was so excited to set up my first planted tank and had everything ready to go. The diffuser leaked at every connection including both ends of the u joint. I tried everything to resolve it… warming the tubing… getting it far up the connections.. super glue. Nothing worked. Tried two of them and both leaked everywhere. Also considered that it could be my tubing.. but as soon as I replaced it with glass joint/diffuser with nipples the problem instantly was resolved so it wasn’t the tubing at all. Product is really poorly designed and will never waste money or cheap out on a diffuser again. Don’t water your money, time, or Co2!

The media could not be loaded.  Hey. After reading a few negative comments, I wanted to share my experience with you all as well. When I first got this, I had some issues with it not pushing the co2 with the bubble count being over 10 a second (yes, ridiculous). HOWEVER, after I let it soak in water for 24 hours, water was able to get into the space under the ceramic disc, allowing the co2 to easily push out at just 1 bubble a second (picture is of one bubble per second).Guys, I cannot stress enough: BE PATIENT! Let it soak, then try again. I seriously thought it was my check valve or my u-bend or, the worst...my regulator. It was just because I wasn't patient enough to allow it to soak. Don't make the same mistake I did. Be patient.

I am amazed at how small this thing is. The disk is about the size of a dime, a little smaller even. The bubbles it creates are so fine that even in my low flow tank, they still move around quite a bit before reaching the surface. With a little flow, they'll make it across the tank no problem. Great price, I'd absolutely buy this again if this one were to break.

The most annoying thing is that the head blew off after a couple minutes and now I have to go return it so they refund me, the micro bubbles were amazing and going through my whole tank, so I will be buying a replacing this one with a new one and hopefully this doesn’t happen again

Muy buen burbujeo en acuario plantado

My C02 diffuser does not diffuse properly. There seems to be poor bondage between the ceramic disc and the plastic, which allows large bubbles to escape at the seams with no diffusion occurring at the surface of the disc.I was hoping that this was just one-off issue with my unit, so I contacted the seller about replacing it, but I was completely ignored.Very disappointed in the product and the customer service, as I initially believed that this was a good brand.

Gekauft, weil die Dinger von vielen auf YouTube hochgelobt werden. Nach meiner Erfahrung aber, zu Unrecht. Angeblich sollen diese Diffusoren sehr feine Blasen erzeugen, das kann ich nicht bestätigen.Man muss Diffusoren immer Zeit geben, aber dieser hier hing schon eine Woche im Aquarium und hat alles andere als feine Bläschen produziert. Absolut nicht zufrieden damit.

Was a bit hesitant because of the price but it’s so simple to set up and use with probable get a second one for cleaning and changing over . Be aware it might be opened like it was by Australian customs thinking it was something else - delayed its arrival by several days
