Review on 🐠 Efficient U.P. Aqua CO2 Inline Atomizer for Aquarium: 3/4-Inch - 16/22mm by Michele Russell

Works great so far. Stick it in the outlet of my Fluval 306 canister. Much better than using a diffuser in an algae growing tank. Very easy to set up and install. Bought a Fluval rubber hose adapter and a check valve to keep water from getting back into my solenoid and that's it! Update: My original started leaking about 8 months after purchase. I noticed that my CO2 tank was getting emptied fairly quickly and when I refilled the tank and plugged it in I heard a very slight hiss coming from the unit (just because I had my closet door open, if it were closed I would have never not heard ). Bought a replacement and it broke IN THE BOX. Obviously a super bad product. It's a shame, because it worked great for the first 6 months! It's time to look for something else.
