UNS CO2 Cylinder Pro

Really happy with the UNC CO2 Cylinder Pro. It feels super solid and high quality, and the design looks really clean next to my tank. Easy to set up and use and works without any issues. Definitely worth it if you want something reliable and nice looking for a planted aquarium. P

Beautiful 5lb Cylinder

This UNS 5lb cylinder is a beautiful part of my CO2 system. It makes me look like a pro! My LFS filled it without issues and it works perfectly paired with the UNS dual stage regulator.

The knob feels awesome. Very well made and looks awesome. Quite very reasonably priced for the quality. Only downside is that most of the places in my area exchange co2 cylinders rather than refill them. The one brewery supply store that does refills requires you to leave the bottle with them for a day. This means there’s a day or two of downtime unless you have a spare to swap in while you get the other filled.
