Not every skimmer has a dedicated CO2 Scrubber Lid available, but that doesn't mean ozone protection is off the table. The Reef Octopus Universal CO2 Scrubber is a standalone acrylic canister that connects to any skimmer's air intake via barbed tubing.
Why a Universal Option Matters
Dedicated scrubber lids are sized to specific skimmer necks, but a standalone canister sidesteps that constraint entirely — it connects via tubing rather than replacing a lid, so it works with skimmers that don't have a matching dedicated lid available.
What It Offers
- Standalone acrylic canister that doesn't depend on a specific skimmer's neck size or lid design.
- Barbed tubing connection that routes intake air through activated carbon before it reaches the skimmer.
- Flexible placement since it isn't mounted directly to the skimmer body.
Setup Tips
- Fill with activated carbon rated for air (rather than water) filtration for best ozone-scrubbing performance.
- Route tubing to minimize kinks that would restrict intake airflow.
- Replace carbon media periodically as it exhausts and stops effectively stripping ozone.
