How It Works
Simply connect the scrubber to your protein skimmer’s air intake.
As air passes through the reactor, CO₂ is removed before entering your system helping to naturally increase and stabilize pH levels.
Why This Matters
Low pH is one of the most common hidden issues in reef tanks, especially in closed homes or during colder months.
By reducing CO₂:
- pH levels rise and stabilize
- Coral growth improves
- Overall tank health becomes more consistent
Key Features
- Designed for use with protein skimmers
- Durable, high quality acrylic construction
- Airtight design for maximum media efficiency
- Compact footprint fits easily under most aquariums
- Dual valve control outlets
- Compatible with most reef setups
Smart Media Indicator
The included IceCap CO₂ media changes color from white to pink when exhausted giving you a clear visual cue when it’s time to replace.
No guessing. No surprises.
Media Replacement
- Typically lasts 2–4 weeks per container (varies by tank & environment)
- Replace once fully color changed
- Do not reuse exhausted media
Pro Tip: Keeping extra media on hand prevents pH swings and keeps your system stable.
Ideal For
- Reef tanks with consistently low pH
- SPS and mixed reef systems
- Homes with high indoor CO₂
- Hobbyists looking to maximize coral growth
