Neo CO2 Aquarium Diffuser - CO2 Diffuser Aquarium Kit, CO2 Diffuser for Aquarium Plants, CO2 System for Aquarium - Normal Special Diffuser, Small

Very nice design, it's durable and produces many micro bubbles.

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

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.

I've personally used neo products. They're great and their diffusers are supposedly one of the best out there in terms of the ceramic they use. I've had this one before but it just so happens I have to give it a 4 star - I returned mine since it had a crack in the glue they use to hold the ceramic plate down. There were big co2 bubbles leaking out. That's just my experience but a non-defective one gets a 5 star.

This product has worked well for me. I soaked the ceramic as recommended on the box. I have been using it with a yeast and sugar diy co2 setup on my 10 gallon. As can be seen from the picture, the tank has done well with the setup. Had I known diy co2 was this good, I would have started using it a year ago. The diffuser works wonderfully for this application. I am not sure what to make of other reviews which had premature failures. All I know is after a month it is still going strong for me.

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. This is a very nice diffuser, very fine bubbles. Love the aesthetics. Just what I was looking for.

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.
