TWINSTARCO2 Diffuser (Small)

Actual item isn't quite 100% as pictured as other reviewers have mentioned; however, the diffuser still does a good job and produces fine bubbles without any leakage. Only reason I didn't rate 5 stars is because it only comes with 1 suction cup which causes the diffuser to swivel/pivot anytime the tubing moves. Not a giant deal, but if you're anal about everything always being symmetrical like me, then it could be slightly annoying with how easy it is to nudge it off center.

The media could not be loaded.  This is my third purchase from Aqua Forest Aquarium, and once again I’m extremely happy with my choice.I ordered another of this diffuser (1 large and 1 medium) for my fish tanks, as I wanted to have a spare for each to swap them out when the other one needs cleaning.These diffusers are EXCELLENT. They do a fantastic job of creating an ultra-fine mist of Co2 bubbles. My plants are thriving, and I know that a good chunk of that happiness is because these diffusers make it easy for the Co2 to get into the water column and thus, to my plants.Their customer service is outstanding, too. I screwed up my order (ordered the small when I wanted to medium), and when I contacted them, they worked instantly and easily with me to make sure I got the correct size.I doubt I’ll have to order another one for a long time, but when I do, this is the only diffuser I will buy.Thanks AFA!

I like how small it is overall. Most importantly, the bubbles are finer than my previous white ceramic/stainless diffusers. I wish the ceramic part came in other colors, eg. white. The only disappointment with this diffuser is that the stem is only like 2 inches. I purchased another diffuser very similar to this but it had a nice long 8"? stem AND it came with a curved connector for the tube that also functions as a clip. So it stays in a fixed position on the tank without any suctions cups at all. So a cleaner look.

Very fine bubbles. It comes out evenly on the entire surface. I got this to replace one that came with my co2 reactor. I was having trouble getting my drop checker to turn green. Put this one on and by the end of the day the drop checker was nearly yellow and I had to turn down my co2 a bit. Definitely works way better than what I had previously.

I was afraid that dirt or algae would block the tiny hole over time but it still makes very small bubbles which is great for saving CO2.

I bought this as a replacement for the stock diffuser that came with my CO2 kit. It has made a world of difference for such a low price. This will definitely be my go-to for my next setup.

Did a great job diffusing co2 from my homemade co2 dispenser. Works well at low pressure. The product is made of a hard plastic making it far more durable than glass.

Works so far. It came with 2 small chips in the top but I used it anyways because it was a cosmetic issue, that’s why I gave it 4 stars instead of 5. I am using it with a diy one bottle yeast and sugar Co2 setup. Love it so far

Buen producto, funcional, justo lo que necesitaba.
