Review on 💨 U.P. Aqua Co2 Atomizer Inline System by Katie Ramirez

This built-in Co2 diffuser has no problem. The other customer's CO2 must have leaked and not holding the pressure. I use a standard 5lb Catalina aluminum CO2 tank with an Aquatek of California regulator and have NEVER had any problems. It goes through an Eheim Classic 2211. The outlet hose on this filter is too small so I installed it at the very top of the inlet as it exits the tank. By the time the suction reaches the canister filter, the bubbles will have completely dissipated and the canister will not make any noise as there are no bubbles. If you run it at the exit of the aquarium, you will still see fog or sometimes bubbles in the aquarium. This will never happen if you set it at the input of the filter. It's just as good as a CO2 reactor, even better because it doesn't reduce your flow like an in-line CO2 reactor and you don't need an additional pump like with overhead CO2 reactors. I highly recommend it. And I'm a professional aquascaper! It also works completely silently.
