Mufan Aquarium sectional Type Stainless Steel CO2 Diffuser + 2 pcs of Replacement diffusing Discs

The media could not be loaded.  This is a solid little stainless steel diffuser. It feels well made and looks nice in the tank. You can easily twist it open to swap out the ceramic disc, which is really good because the disc is the part that determines your bubble size and those discs are NOT all created equally.I bought the diffuser from this seller specifically because they were selling it with two extra discs. The disc that was already inside the diffuser when I received it produced large bubbles and was pretty useless. I swapped it out for one of the extras that came with it and that one produces an excellent mist of tiny bubbles.In my experience, the ceramic in any diffuser is hit or miss. If you can’t swap out your disc, then that means you’re just stuck with what you have. That’s why I really like that this type of diffuser makes it easy to swap out the disc and that you get two extras with this purchase.I attached a shot of the diffuser in action in my tank, after I changed out the first disc.

Works well. Difuses bubble in a uniform, small bubble style. Although I didn't see In the directions, I did leave the diffuser soaking in water for 30 minutes+. Most diffusers will State to soak the diffuser prior to using it. Maybe that's why some folks are experiencing inconsistent bubble's. Just a thought.

everyone single one clogged within 2 days of use. waste of money! Buy a steel oe designed for beer brewing instead!

Work like the description, easy to install.

3 spare discs.only one working.and rubber seal doesn't work good need tide well

Leaks too much. The seal around the ceramic disks is. It tight enough- it leaks large bubbles. Would not recommend

I was not able to tighten it enough to not have large co2 bubbles leaking out around the top seal of the disk.

Its good and the extra ceramics are bonus too.
