IceCap Color Changing CO2 Absorbent Media is a high-performance solution designed to combat chronically low pH levels in saltwater reef aquariums. When used in a CO2 scrubber connected to a protein skimmer's air intake, this media effectively removes carbon dioxide from the air entering the aquarium. By scrubbing CO2, it helps to naturally and safely raise the pH of your tank's water, creating a more stable environment that encourages faster and healthier coral growth.

This user-friendly media features a distinct color-changing indicator to visually signal when it is exhausted and needs replacement. The pellets will transition from white to a vibrant pink or purple as they become saturated with carbon dioxide, eliminating guesswork. IceCap has formulated the media into a perfectly pelletized size that minimizes dust while maximizing airflow and efficiency within the reactor, ensuring consistent performance and preventing clumping.

This product is ideal for any reef aquarist, from beginner to expert, who is frustrated by low pH despite maintaining proper alkalinity. It's particularly beneficial for tanks in well-sealed homes or rooms with poor air exchange, where ambient CO2 levels can suppress aquarium pH. For hobbyists seeking a simple, affordable, and effective method to stabilize their water chemistry and unlock their corals' full potential, this CO2 absorbent media is an essential tool.
