Conventional Bubble Counter

I LOVEEE this. The best part is that it has the built-in check valve, so you don’t have to buy one separately, which just makes everything way easier and cleaner to set up. It works exactly how it’s supposed to, and the bubble counting is clear and consistent. The quality also feels really solid, not cheap at all, so I feel comfortable using it long-term with my setup. Honestly just super convenient and one less thing to worry about when setting up CO2. Definitely recommend if you want something simple and efficient.

The carbon dioxide bubbler works great. It keeps a constant flow of CO2 in our tank which is great for the plants. It was great value for the money, easy to install, and works consistently.

Well made. I have 1 from a different brand and the threads stripped out fast and it leaked water back into my co2 tank. This 1 is working great so far.

Not too expensive. Has a small o-ring inside it--have no idea how to use it. Anyways, installed it and there are no leaks. I would NOT recommend you unscrew the bottom. THe check valve parts will fall out and can be lost easily. Don't do it!!!

I bought two of these about 4 months ago. They seemed pretty good at first but they got very unreliable after a while. The difference between no flow and a stream of bubbles wasn't even a full turn. Then I noticed the flow rate would go up over time. Got busy and didn't check it for a few days and it had went up high enough to drain 2/3 of my cylinder in just a few days, the first third lasted months. But it was only one of the two that kept feeding more, the other one tended to feed less after some time.

I used the dual needle valve splitter from this brand to add an output to my UNS regulator. I went with this bubble counter to save a couple bucks and I wish I had gone with the UNS one for the matching look. The first day this was set up I had a lot of water back up through my clear tubing and I assumed the check valve was cheap and faulty. I went through and tightened everything more than what I would call finger tight, and now it works as well as the UNS bubble counter. Overall it works as expected but it shows that it’s not as nice as the UNS one which is a masterpiece in form and function comparatively.

Works great and easy to install. Added to Fzone CO2 generator as 2nd output

Work great good quality affordable I have 2 no leaks just a product overall

Llego en tiempo y los materiales son de buena calidad, hasta ahora ha funcionado Perfecto!
