The Universal CO2 Scrubber is an essential tool for reef aquarists looking to stabilize and raise their aquarium's pH levels. By connecting directly to your protein skimmer's air intake, this device actively removes excess carbon dioxide from the air before it enters your tank. Since high ambient CO2 is a primary cause of low pH in home aquariums, scrubbing the air can lead to a more stable environment, promoting faster and healthier coral growth by maintaining optimal pH.

This reactor features a durable body with a refillable internal cartridge designed to be filled with your preferred CO2 absorbent media. It includes 3/8" tubing for a straightforward connection to most protein skimmer venturis, often replacing the skimmer's silencer. The design is simple to set up and maintain, requiring only the periodic replacement of the CO2 media. This unit is specifically designed for use in saltwater aquarium systems and is backed by a one-year warranty, ensuring reliable performance.

This product is ideal for any reefer struggling with chronically low pH, especially those whose tanks hover at 7.8 to 8.0. It is particularly beneficial for aquariums located in well-sealed homes or rooms with poor air circulation where ambient CO2 levels are elevated. For hobbyists who find it impractical to run an airline from outside, a CO2 scrubber offers a direct and effective solution to raise pH by several points, often up to the ideal range of 8.2-8.3, creating a much better environment for coral calcification and overall health.
