CO2 Scrubber Skimmer Lid 6" (C2C-150)

The Reef Octopus CO2 Scrubber Skimmer Lid 6" (C2C-150) replaces your skimmer's standard vented lid with a sealed port that routes intake air through a CO2 scrubber canister rather than pulling directly from room air — useful in enclosed fish rooms or poorly ventilated spaces where elevated indoor CO2 can drag tank pH down. Fits: Reef Octopus skimmers with a 6-inch (150-size) neck Use: connects to a CO2 scrubber canister (media sold separately) to feed scrubbed air to the skimmer's air intake Running a skimmer on scrubbed air rather than ambient room air is one of the more overlooked fixes for chronically low pH in enclosed fish rooms. Compatible with: Reef Octopus skimmers using a 6-inch (150-size) neck and lid.
