IceCap Aquarium CO2 Absorbent Media, 1 kg Colour-Changing Pellets for pH Support

IceCap Color Changing CO2 Absorbent Media is aquarium scrubber media designed to help manage CO2 and raise aquarium pH, in a 1 kg pelletized format that changes pink when used up.

• 1 kg of CO2 absorbent media — supplies media for a compatible CO2 scrubber.
• Calcium hydroxide and sodium hydroxide mixture — absorbs CO2 as part of a scrubber setup.
• Turns pink when used up — provides a visible replacement cue.
• Pelletized media — designed for minimal dust and maximum performance.
• Used with a CO2 scrubber and protein skimmer — connects the scrubber to the skimmer’s air intake.

Low aquarium pH can be a concern for reef keepers, including those frustrated by slow coral growth. IceCap media is intended for a CO2-scrubbing setup to help control carbon dioxide and raise aquarium pH. It is a consumable media, not a standalone device: a CO2 scrubber and protein skimmer are required for use.

What is IceCap CO2 Absorbent Media designed to do?

It is designed to absorb CO2 in a scrubber system and help raise aquarium pH. The media is a precise mixture of calcium hydroxide (Ca(OH)₂) and sodium hydroxide (NaOH). Its color-change feature gives you a visual cue for when the media has been used up.

• Intended for aquarium CO2 control and pH management.
• Supplied as a 1 kg quantity of media.

What equipment do I need, and how does it connect?

You need both a CO2 scrubber and a protein skimmer to use IceCap media. Attach the tubing supplied with the scrubber to the skimmer’s air intake, then connect the tubing’s other end to the scrubber. The media works within this connected setup rather than on its own.

• Compatible setup: a CO2 scrubber connected to a protein skimmer.
• The tubing used for the connection comes with the scrubber.

How do I know when to replace the media?

Replace IceCap media when it turns pink or when aquarium pH drops. These are the two replacement cues given for this media; the color change lets you monitor the media visually, while a pH drop is another reason to change it.

• Pink color indicates the media has been used up.
• A drop in aquarium pH is also a replacement cue.
• The pelletized form is designed to minimize dust.

IceCap Color Changing CO2 Absorbent Media suits aquarium keepers who already use, or are setting up, a CO2 scrubber with a protein skimmer and want a visible indication of media use. It is intended for that connected aquarium setup, and its pink color change and pH-drop guidance help identify when replacement is due.
