The quality of the materials used in this diffuser really blow me away. It feels like something that was designed with function rather than cost of production in mind.
Quality, materials, construction and design are top notch. Superior to any plastic inline diffuser hands down. No issues with install, love that I can see when to clean it, as well as being much easier to clean. As advertised, only micro bubbles if any. I would buy again without hesitation.
I have a 200 gallon planted tank and need to diffuse a lot of CO2. This metal diffuser is much better than the plastic one I had before and does a good job. Good quality.
I have used by all the plastic inline diffusers on the market. They all break at the threads or incoming co2 nipple eventually.. Finally GLA is the first to make an aluminum one!
