4 star review. not 5 because initially the connection between the tubing and diffuser leaked nearly all the co2. I acknowledge this may be more of a problem with the tubing and not the diffuser however I am using the tubing sold from aquarium co op. I solved the leak problem by shoving the suction cup holder on the diffuser over the air tubing line on the connection (see picture). Now it works great with no leak. Aquarium co op is a great company with great products. However, one area for improvement may be air lines and check valves for co2 equipment.
One of the Best I have ever used really have to give Mr.Cory a big Thank You for the honesty of his business
Great diffuser but if anyone knows how to clean it let me know. Thanks!
Works amazing and starts up quickly. I would recommend this diffuser over the fluval diffuser.
I have used a cheap glass diffuser, and the Fluval one, these seem to start flowing easier, don't grow algae, and don't seem to take as much pressure to work as the fluval. Plus built in bubble counter.
