UNS CO2 Cylinder Pro

New and as advertised

Ordered two UNS CO2 cylinders from Glass Aqua (1 10# and one 5#) and both arrived in excellent condition with OEM manufacture dates within 1 year of purchase (to be filled/re-filled CO2 cylinders must be hydro-pressure tested every 5 years or so (~US$40), depending on your local jurisdiction, so this matters!). The white finish looks waaaay better than the usual dinged up aluminum cylinders do. . . if your cylinders are exposed, lol. Good stuff.

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.
