Review on 🌿 Rhinox Nano CO2 Diffuser: Hassle-Free Setup for Healthy Aquarium Plants with Pressurized CO2 - Ideal for Tanks Under 20 Gallon by Carrie Anderson

This is for a 5 gallon diffuser. Looks good but makes a rattling noise when working. I get a finer mist from my linden diffuser, so I'll probably come back to that. In addition, this diffuser requires a significantly higher pressure than my basswood diffuser. Edit: After dithering for a while, I'm upgrading it to 4 stars. It constantly produces tiny little bubbles unless the river overflows it. Basswood no longer seems to release tiny bubbles when the flow exceeds negligible amounts. The downside to this is that it creates significant pressure in the system, which means that changes in the outlet pressure of my Aquatek Mini CO2 Regulator are often not immediately reflected in the change in bubble velocity. I don't know why, but I suspect the pressure required to force the CO2 through the ceramic might have something to do with it.
