IceCap Small CO2 Scrubber pH Upflow Reactor (IC-CO-50)
The IceCap Small CO2 Scrubber (SKU: IC-CO-50) is an authentic, ultra-compact water care
reactor distributed by CoralVue to unlock optimized coral calcification and accelerate
skeletal growth rates in space-conscious reef systems and nano aquariums. In modern
well-insulated homes and offices, pet and human respiration causes ambient indoor carbon
dioxide (CO2) concentrations to rise drastically above natural outdoor air levels. When your
protein skimmer draws this unrefined air into its high-speed venturi, the gas instantly
dissolves into the water column, creating an ongoing influx of carbonic acid (H2CO3). This
acid actively depresses your baseline pH. Low pH forces corals to expend significant metabolic
energy just to build their calcium skeletons, stalling overall growth and causing problematic
daily parameter swings. The IC-CO-50 breaks this cycle cleanly and affordably in a true
miniature form factor.
Featuring a heavy-gauge 4-inch clear acrylic body housing with a compressed height profile,
this small-scale scrubber serves as a high-contact chemical air filter. You simply hook up the
included air tubing from the top output port of the reactor directly to the air intake on your
skimmer pump (bypassing or removing your stock skimmer silencer cup). As the skimmer pump
naturally sucks room air through the reactor base, the air cascades upward through a 1.1-pound
bed of soda lime pellets. This dense reactive matrix traps the gaseous carbon dioxide on
contact, locking it into solid calcium carbonate. Only pure, CO2-stripped oxygen is allowed
to enter your skimmer's bubble chamber. Designed specifically for tight cabinet setups,
desktop stands, and all-in-one rear chambers, the Small Scrubber provides a stable,
predictable solution to maintain a rock-solid 8.3 pH baseline.
Key Features:
Built-In Secondary Deflector Plates: Integrated interior baffle plates guide
incoming air uniformly across the entire media chamber, preventing air from "tunneling" up
a single side.
High-Clarity Heavy Canister: Transparent structural wall construction permits
instant visual checks on your media bed's color shift indicator from across the room
without popping the seal.
Ultra-Compact Form Factor: Standing at just 6.5 inches tall, it squeezes into
tight configurations where standard medium or large inline media scrubbers physically
cannot fit.
Note: This filtration package includes the standalone small reactor body, integrated
bracket assembly, 3/8-inch fittings, and connecting airline tubing. High-volume replacement
color-changing media jars are sold under separate product categories.
