For many marine and freshwater aquarists, running a dedicated macroalgae refugium is impossible due to space constraints or the lack of an under-cabinet sump. The IC-AGS-50PRO bypasses these limitations by packing high-capacity turf algae scrubbers into a compact, rim-mounted profile. By forcing your water column to pass directly over a targeted, highly illuminated growth matrix, the scrubber causes hair algae, film algae, and organic compounds to grow \u003ci\u003einside\u003c\/i\u003e the box rather than over your decorative display rockwork.\u003c\/p\u003e\u003cp\u003eOperation is straightforward and efficient: the bundled IceCap EVO-400 utility pump sits submersed inside the tank, delivering up to 105 GPH of water directly into the scrubber's internal spray bar. This water trickles down a heavily textured, laser-roughened mesh growing screen that is lit from both sides by high-efficiency photoperiod grow lights. As the algae mat matures, it acts like a sponge, pulling dissolved inorganic nitrogen and orthophosphates straight out of the water column. Scraping the screen clean every 1 to 3 weeks permanently extracts these bound pollutants from your system. This significantly reduces your dependency on artificial chemical resins and frequent, labor-intensive water changes.\u003c\/p\u003e\u003ch3\u003eKey Features:\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eStabilizes Daily pH Fluctuations:\u003c\/b\u003e When programmed to run on a reverse photoperiod opposite your display lights, the algae's overnight photosynthesis consumes carbon dioxide, preventing morning pH drops.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eUniversal Rim Tracking Adjustment:\u003c\/b\u003e Adjustable mechanical tracking brackets safely accommodate standard plastic-molded or rimless tank edges ranging from 1\/4-inch to 1 3\/8-inches wide.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eDual Emergency Overspill Tracks:\u003c\/b\u003e Features a secondary relief pipe that handles high water levels if heavy algae growth blocks the primary drain slot, keeping your living room floor dry.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003ci\u003e(Note: This self-contained HOB assembly arrives complete with the main black polymer reactor box, internal textured mesh grid, dual 6W LED light modules, a 24V DC power transformer, and an EVO-400 pump).\u003c\/i\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eVerified System Performance Specifications\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cp\u003e\u003cb\u003eTarget Aquarium Rating:\u003c\/b\u003e Explicitly rated to manage biological loads on standalone systems up to \u003cb\u003e80 Gallons\u003c\/b\u003e.\u003c\/p\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eOnline exclusive: this item is ordered in for you and is usually ready within a few business days.

Maintaining chemical filter media—especially granular ferric oxide (GFO) for phosphate export and granular activated carbon (GAC) for organic tracking—is essential for avoiding nuisance algae outbreaks.

This adjustment flexibility lets you dial in the exact water movement your media needs, from a gentle surface shimmy for fragile carbon granules to a high-velocity tumble for dense biopellet strings. Maintenance is completely tool-free: simply pull off the splash cap, slide out the inner twin-chamber cartridge, and dump spent media directly into your sink.

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 (H2​CO3​). 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. \u003c\/p\u003e \u003cp\u003e 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. \u003c\/p\u003e \u003ch3\u003e Key Features: \u003c\/h3\u003e \u003cul\u003e \u003cli\u003e\u003cp\u003e \u003cb\u003e Built-In Secondary Deflector Plates:\u003c\/b\u003e Integrated interior baffle plates guide incoming air uniformly across the entire media chamber, preventing air from \"tunneling\" up a single side. \u003c\/p\u003e\u003c\/li\u003e \u003cli\u003e\u003cp\u003e \u003cb\u003e High-Clarity Heavy Canister:\u003c\/b\u003e Transparent structural wall construction permits instant visual checks on your media bed's color shift indicator from across the room without popping the seal. \u003c\/p\u003e\u003c\/li\u003e \u003cli\u003e\u003cp\u003e \u003cb\u003e Ultra-Compact Form Factor:\u003c\/b\u003e Standing at just 6.5 inches tall, it squeezes into tight configurations where standard medium or large inline media scrubbers physically cannot fit. \u003c\/p\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e \u003ci\u003e Note: This filtration package includes the standalone small reactor body, integrated bracket assembly, 3\/8-inch fittings, and connecting airline tubing.

While typical filtration protocols rely on synthetic chemical resins or mechanical media that require constant replacement, an Algae Turf Scrubber (ATS) works on a simple, eco-friendly premise: fighting algae with algae. By creating a perfect micro-environment specifically optimized for high-speed green hair algae growth inside an enclosed chamber, the system forces the algae to consume local nitrate and phosphate ions directly from the moving water. This stars out unmanaged hair algae and cyano blooms inside your primary viewing display.\u003c\/p\u003e\u003cp\u003eWhat elevates the IceCap PRO External Scrubber line above traditional, open-box DIY alternatives is its \u003cb\u003eEnclosed Internal LED Engine\u003c\/b\u003e.

The IC-AGS-1EXTPRO incorporates specialized, dual-sided 24V grow LED panels completely enclosed within the watertight acrylic frame itself.

Traditional approaches to nutrient management typically rely on chemical resins, liquid carbon dosing, or massive water changes, which can destabilize baseline water chemistry or strip trace minerals.

Water is fed up into the top intake by the included \u003cb\u003eIceCap EVO-2000 Feed Pump\u003c\/b\u003e. This water enters a custom-slotted PVC spray bar and trickles down a rugged, double-textured plastic screen mesh. This mesh is illuminated on both sides by high-intensity, double-sided 15W LED growth panels engineered to output the ideal wavelength spectra for green hair algae growth. As the algae mats colonize the screen, they aggressively absorb free ammonium, nitrates, and orthophosphates directly from the water column. Once the screen fills up, simply lift out the screen, scrape the algae into a waste bin, and drop it back in—permanently exporting pollutants out of your marine ecosystem entirely.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eStabilizes Aquarium pH Wavelengths:\u003c\/b\u003e Running the integrated LED growth panels on a reverse photoperiod counteracts the natural nighttime CO2​ spikes of your display tank, stabilizing baseline pH values.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eZero Sump Intrusion Profile:\u003c\/b\u003e Mounts entirely outside of your filter sump compartments, preserving precious internal real estate for large protein skimmers, media reactors, or return pumps.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eSplash-Free Gravity Drainage:\u003c\/b\u003e Directs water smoothly back down past your sump lip via a large-diameter plumbing track, ensuring silent operation and low salt spray accumulation.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003ci\u003e(Note: This retail package arrives with (1) Large External Scrubber body with lid, (1) rough-textured turf screen, (1) slot-cut spray bar with quick-union, (2) 15W waterproof LED panels with power adapter, and (1) EVO-2000 water feed pump.

Traditional kalkwasser dosing requires hobbyists to manually mix white powder into large top-off reservoirs or reservoirs. This not only consumes substantial space under the cabinet but exposes the solution to room air, where carbon dioxide immediately reacts with the lime water to form a useless calcium carbonate precipitate crust, rapidly reducing its potency. The IceCap KM-200 completely eliminates manual daily mixing by isolating the calcium hydroxide within an airtight, compact structural tower.\u003c\/p\u003e\u003cp\u003eAt the operational core of the Large Kalk Mixer is its advanced \u003cb\u003eAdjustable Speed Magnetic Stirrer Motor\u003c\/b\u003e. Standard kalk stirrers use traditional internal water pumps to mix the slurry, which quickly wear down or freeze up as calcium scales form along the impellers. The KM-200 utilizes a completely isolated external motor that drives a heavy-duty internal magnetic stir bar coated in reef-safe polymer. Hooked up to an external timer or controller, the mixer automatically turns on a few times a day to gently agitate the powder bed at the base, creating a highly concentrated, super-saturated fluid layout. When your fresh Auto Top-Off (ATO) pump pushes fresh water into the reactor base, it forces the clear, rich kalk solution out of the top gravity port and down into your sump, providing balanced calcium and alkalinity while maintaining a stable pH level of 8.3 inside your display.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eAggressive pH and Nutrient Support:\u003c\/b\u003e Delivers a high-pH solution that binds free phosphates while neutralising organic CO2​ inside the aquarium loop to maximize coral growth rates.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eSafe, Non-Pressurized Discharging:\u003c\/b\u003e Employs a zero-pressure gravity flow design that limits structural strain, eliminating the messy floor leaks common with pressurized filters.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eHeavy-Wall Acrylic Engineering:\u003c\/b\u003e Constructed from thick, durable clear cell-cast acrylic panels anchored securely onto a heavy, high-gloss solid PVC support plate.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003ci\u003e(Note: This retail package includes (1) Large Kalk Mixing Reactor vessel, (1) integrated magnetic drive motor, (1) internal magnetic stir bar, (1) low-voltage power supply, and push-fit plumbing adapters.

In massive reef aquariums packed with fast-growing small polyp stony (SPS) corals, mineral uptake can easily exhaust traditional liquid dosing regimens, spiking monthly maintenance costs and destabilizing water parameters.

When executing water quality management on a commercial scale, standard hobbyist reactors quickly fall short under dense biological coral loads. The CR-250PRO resolves this limitation by introducing an automated, high-capacity fluidizing column.

Achieving an optimal pH threshold of roughly 8.3 is essential for maximizing coral growth rates, skeletal density, and overall metabolic vitality. However, modern heavily insulated homes trap localized carbon dioxide from human respiration, which is constantly sucked in by protein skimmer venturis. This excess CO2 dissolves directly into the water column, turning into carbonic acid and driving pH levels down. By routing your skimmer’s fresh air supply line straight through this high-capacity carbon dioxide scrubbing chamber, ambient CO2 is chemically stripped before it can compromise your water chemistry.\u003c\/p\u003e\u003cp\u003eMolded from structural, transparent premium acrylic, this genuine Reef Octopus reactor forms a strictly airtight environment that preserves the potency of color-changing CO2 media. The design includes an adjustable, built-in manual bleeder valve on the top cover cap, providing precise air induction control. The OCT-C2T90 is uniquely optimized for closed-loop recirculation setups when paired with a matching model-specific Reef Octopus skimmer collection lid adapter. Rather than drawing high-volume humid external air continuously, the closed-loop configuration recirculates moisture-rich, low-CO2 air directly from the collection cup. This humid environment prevents the media from drying out prematurely, expanding its lifespan and reducing your long-term operational costs.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eMaximized Coral Calcification:\u003c\/b\u003e Accelerates stony coral skeleton building by preventing the daily pH drops typical of indoor aquatic systems.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eFlexible Recirculating Architecture:\u003c\/b\u003e Native barbed hose manifolds support simple conversions into ultra-efficient, media-saving closed loop setups.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eTool-Free Media Servicing:\u003c\/b\u003e Quick-disconnect true union collar rings allow fast removal of the internal diffuser sponge plates during media changes.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eAirtight Structural Seals:\u003c\/b\u003e Heavy-duty, chemical-resistant interior rubber o-rings isolate gas pathways, preventing raw basement air bypass leaks.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eDurable Industrial Hardware:\u003c\/b\u003e Resists structural fatigue, salt creep cracking, and localized chemical decay inside high-humidity sump cabinets.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTarget Performance Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003eDesigned to safely support a massive array of small, mid-size, and heavy commercial consumer protein skimmers when matched to appropriate air tubing lines.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eCan be operated as a standard ambient draw filter or transformed into a highly advanced recirculating framework when paired with custom Reef Octopus C2C collection cup replacement lids.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eOnline exclusive: this item is ordered in for you and is usually ready within a few business days.
