Review on Super Aquarium Fish Tank Equipment: CO2 Atomizer Diffuser for Carbon Dioxide Dispersion (Large-Brown) by Kayty Michaels

This diffuser lasted almost 3 months. While this limited the amount of CO2 emitted, the results were consistent and the bubbles were in fact microbubbles. Then, about an hour ago, I misadjusted it a bit (literally turned it about 1/4 turn because it was hit askew by a fish) and it started bleeding CO2 from the screw sleeve. Trim the new line to ensure this is not a problem, re-tighten, re-tighten, etc. Now the CO2 is only escaping from the injection area (obviously no diffusion). Very disappointed.
