The Reef Octopus CO2 Scrubber is a universal reactor to help control pH levels within a reef aquarium by lowering the concentration of dissolved carbon dioxide in the water. The ideal pH level for a reef tank should be around 8.3 for optimal coral growth. If your aquarium suffers from chronically low pH or you find it challenging to keep pH within the desired range, connecting a Reef Octopus CO2 Scrubber to the air intake of your protein skimmer is a great solution to increase and maintain your levels.


If you'd like to increase the longevity of your CO2-absorbing media* when using the reactor, be sure to check out the moisture-reducing CO2 Scrubber Skimmer Lids to be used in conjunction with Reef Octopus Protein Skimmers.

*Note: CO2 absorbent media is not included.
