UNS Pro Inline CO2 Diffuser

The UNS Inline Diffuser is saving me a bunch of money on CO2. I was using the ADA CO2 Advanced System Forest with the Pollen Glass EZ bubble counter/diffuser. It was working fine, although I was changing the cylinder about weekly on a 60H heavily planted tank. I just wanted an inline for a cleaner look in the aquarium. I just switched the diffuser to the UNS Pro Line inline CO2 diffuser and had to reduce the CO2 input since the UNS was much more efficient. Highly recommended for a 60H aquarium.

Great way to inject CO2

Amazing quality and great way to inject co2 with ease. Bubbles I’m in co2 injected very tiny. Great quality. UNS is a great selection.

A definite upgrade

I was happy with my first CO2 diffuser, the standard-issue Aquario Neo model. It did a good job, but I felt that too many CO2 bubbles were escaping to the surface. That prompted an upgrade, to the UNS Pro Inline diffuser. The bubbles are definitely finer, and they make it all the way across the tank before dissipating. The plants love it, and I do too!
