Reef Octopus Universal CO2 Scrubber

The Reef Octopus Universal CO2 Scrubber is a standalone acrylic canister that connects to any skimmer's air intake via barbed tubing, rather than requiring a specific lid adapter like the C2C series. It scrubs incoming air of CO2 before it reaches the skimmer, helping stabilize pH closer to the ideal 8.3 range for coral growth.

• Best for: hobbyists wanting CO2 scrubbing on a skimmer without a compatible C2C lid available
• Construction: durable acrylic body, hermetically sealed to preserve scrubbing media potency
• Controls: dual valve control for airflow adjustment
• Connection: universal barbed intake fitting, compact footprint for easy placement

Being "universal" rather than lid-specific means this scrubber works with skimmers outside the Reef Octopus C2C lid compatibility list — useful if you're running a different brand's skimmer alongside Reef Octopus equipment.

Compatible with: any protein skimmer air intake (universal barbed connection).
