AquaFinder CO2 Diffuser Glass for Aquarium/Fish Tank

Great diffuser for the aquarium hobbyist. Small bubble size, and works roughly as a bubble counter as well. Plants have been growing amazing since I added the CO2 system. Not nearly as pricey as some of the other diffusers out there, and it's pretty easy to hide behind plants or hardscape if you wish.

I love diffusers, just make sure you get a little water in the line, instant bubble counter, and visual aid to see how much co2 is going out. The suction cups are not the best.

Forget the full-length CO2 diffusers. They cost more, they don't fit on the side of the standard black rim tank (who designs these things?) and they break just from putting the tube on. These mini half ones are significantly better as they attribute to none of these things. They also can be hidden much easier than your full-length co2 diffuser. I highly recommend for the planted tank!

Real glass, small but does the job 100%, perfect for 20 Gallon Fish Tank, A+++

I just received this CO2 Diffuser and I'm super impress, I really did not expect the super tiny almost none existent bubbles. It really looks like mist going in the water. I am really glad I got this. The one thing is that the 2 suction cups where missing in my order :-( but I'm sure is just a simple mistake and hopefully i get them soon. Overall great product really excited to see the results on my high tech planted tank.

At first, I thought it was not working properly. I tried blowing through this and it seemed not to be working (and yes I was blowing in the correct direction). Then I installed a cheap check valve in my CO2 system and all it did was leak because of the pressure. So I went ahead and tried this check valve and it works perfectly with no leaks. I guess you need to have it under more pressure than just trying to blow through it.

Works as it should. However, the suction cup was useless and didn't hold the diffuser straight up and down. It kept angling to the side because the suction cup didn't have a stronghold on the glass tube. I ended up using a different suction cup that had been on my previous diffuser that worked better.

I picked this up to replace an old diffuser I frankly was aged and not sticking to the tank for a while. Thus far I must say I'm very pleased with the suction cups, work nicely to secure the diffuser and the bubbles are decent. I had to back my CO2 down due to the shrimp not handling it well and when I did so I noticed they became a bit larger. However, when I had the CO2 cranked up the bubbles were very fine.
