Reef Octopus Classic 110-SSS Co2 Attachment

Works really well.

Fits perfect on my skimmer and works really good, however will need some sort of collection chamber for moisture. Scrubber gets wet from recirculating.

Hreat quality and fast shipping

Perfect fit

Used this as a part of the co2 scrubber setup I purchased to help with my chronically low pH. Perfect fit for the skimmer. Very high quality 3D printed items. Impressed.
