This diffuser only works with an external filter. You cut the drain hose and insert the device so that it is in line with the return. It is best next to the external filter so that the microbubbles can dissolve even more. As you walk in the water, you can barely see the fine mist, which appears much smaller than the bubbles emerging from these cup-shaped glass diffusers. . I have an Eheim Classic 2213 external filter and the 12/16mm fits perfectly. In my setup it lasted about 5 months before I had to clean it, which can be done in a mild bleach solution for 24 hours. I ended up buying a second one so I wouldn't have downtime for a canister filter or CO2 injection. The only downside is the high price as it's just a piece of plastic with a ceramic insert.
