External Inline CO2 Diffuser Atomizer Aluminum Alloy for Planted Aquarium 16 mm

I been using co2 inline for a while now, the ceramic cylinder type one, i was a starting to loosing performance, I was due for maintenance.. So. While one is in service, I would have one in bleach solution for cleaning, so I tough why not purchase another one.. Based on Amazon recommandation and many positive review i had really high hope and excited to try this one.. Delivery came, started reading instructions, inspecting the diffuseur, I tried screwing co2 line into it for test fitting, screw it firmly and the tip broke.. Didn't even have the chance to try it out.. So just for that I would be giving it a 1 start rating for fast delivery... And minus 4 star for quality of product. Let's hope it's only a assembly or quality control problem and I was just badlucky, other user won't have water leak down the road 😉

Works good. Only issue is the front view window traps air bubbles.

This thing was great to start... less impressed over time. It started to build up algea and debris on the diffuser disc just like the ones in the tank. I thought this one wouldn't since it was in the filter line; I also kept it covered from light but it still got build up. It took longer but alas, still did. Changing the disc requires you to open the line which means a watery mess. I ended up switching to a different system.

Funciona pérfectamente, sin goteso, facil instalacion y acabados perfectos.....feliz con el producto ya quedo mas limpio mi acuario de elementos que afean su interior.

This product states it can be rotated and used horizontally but that did not work for me. Drop checkers, even right next to my filter outflow, stayed blue. At an insane number of bubbles per second, large bubbles flowed through, but not anything under 10 bubbles per second. I had the PSI above what was specified, as high as 35 at one point, but the horizontal orientation didn’t work. I rotated it back and it did work, but I had to rearrange things for that to work.
