IceCap CO2 Scrubber - Medium The IceCap CO2 Scrubber - Medium is a reef aquarium CO2 scrubber designed to connect to a protein skimmer air intake and help reduce carbon dioxide entering the aquarium system. With a taller 4 inch body and approximately 1kg media capacity, it provides more absorbent media volume than the small model while keeping the same compact footprint. Medium IceCap CO2 Scrubber Overview This medium IceCap CO2 Scrubber is a strong middle-size option for reef aquariums that need longer media contact and more media capacity without moving to the larger 5 inch body. It is useful for hobbyists dealing with low pH caused by high indoor CO2, especially when a protein skimmer is already running and can pull air through the scrubber media. Medium CO2 Scrubber Features Helps reduce CO2 drawn into the protein skimmer to support higher reef aquarium pH. Approximate 1kg media capacity offers increased media volume over the small model. 4 inch body keeps the same 4.5" x 4.5" footprint while adding extra height. Hang-on bracket allows convenient placement in many sump and cabinet layouts. Works with IceCap CO2 absorbent media or other compatible CO2 removing media. Color changing media helps make exhaustion easier to see during routine maintenance. Suitable for reef systems where skimmer air intake CO2 reduction is preferred over outside-air routing. IceCap CO2 Scrubber - Medium Specifications Product type: Protein skimmer air intake CO2 scrubber Part number: IC-CO-100 Body size: 4 in Media capacity: Approx. 1kg Footprint: 4.5" x 4.5" Height: 9.5" Hang-on bracket: Included Application: Reef aquarium pH support through CO2 reduction at the skimmer air intake Medium Scrubber Compatibility Notes The IceCap CO2 Scrubber - Medium should be connected to a protein skimmer with an accessible air intake line. Make sure the skimmer continues to draw air freely after installation and check for any restriction caused by tubing, media packing, or moisture. Media replacement timing depends on room CO2 level, skimmer air draw, aquarium size, and pH demand. Installing the IceCap Medium CO2 Scrubber Mount or position the scrubber near the skimmer, remove the lid, add CO2 absorbent media, and connect the skimmer air intake to the scrubber output. Tighten the lid, verify normal skimmer operation, and monitor pH closely during the first several days. Replace media when the colour change shows exhaustion or when aquarium pH begins to fall again.
