The Reef Octopus CO2 Scrubber Skimmer Lid (C2C-220) 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 basements where elevated indoor CO2 can drag tank pH down.
Fits: Reef Octopus skimmers with a 220-size neck
Use: connects to a CO2 scrubber canister (media sold separately) to feed scrubbed air to the skimmer’s air intake
If pH swings track closely with when doors and windows in the fish room stay closed, ambient CO2 — not tank chemistry — is the likely cause, and scrubbing intake air addresses it directly.
Compatible with: Reef Octopus skimmers using a 220-size neck and lid.
