IceCap Color Changing CO2 Absorbent Media

The IceCap Color Changing CO2 Absorbent Media removes carbon dioxide from the air before it reaches your protein skimmer, which raises and stabilizes pH in marine and reef aquariums. Tightly sealed modern homes trap CO2 from people, pets and HVAC systems, and a skimmer pulls that CO2-rich air into its venturi, where it dissolves as carbonic acid and drives tank pH down. Running the skimmer air line through this media scrubs out the CO2 so your pH climbs back into a healthy reef range. Explore more reef gear at Squeaky's Aquatics.

Why It Works

• Raises and stabilizes pH: strips CO2 from skimmer intake air, a common cause of chronically low reef pH.
• Color-changing indicator: the media changes color as it is used up, so you can see at a glance when it is time to replace it.
• Chemical-grade absorbent: authentic, high-quality CO2 scrubber media distributed by CoralVue.
• Simple to run: fill a CO2 scrubber or reactor and plumb it inline on your skimmer air intake.
• 1 kg refill: a full 1 kilogram (2.2 lb) container of loose media.

How to Use

1. Fill a CO2 scrubber or media reactor with the absorbent media.
2. Connect the scrubber inline on your protein skimmer's air intake line.
3. Watch the media color and your tank pH, and replace the media once it has fully changed color.

FAQ

What does it do?
It scrubs CO2 out of the air your protein skimmer pulls in, which raises and stabilizes aquarium pH.

How do I know when to replace it?
The media changes color as it absorbs CO2. Replace it once it has fully changed color.

Do I need a CO2 scrubber to use it?
Yes. Load the media into a CO2 scrubber or reactor and run it on your skimmer's air intake.

Freshwater or saltwater?
It is used on marine and reef aquariums, where protein skimmers and pH stability matter most.
