IceCap GFO 150INT Internal In-Sump Media Reactor (IC-GFO-150INT)
The IceCap GFO 150INT Media Reactor (SKU: IC-GFO-150INT) is an authentic, large-format chemical filtration system distributed by CoralVue to provide seamless, internal water purification in high-volume freshwater sumps and large marine reef aquariums up to 500 gallons. Utilizing advanced loose filtration media—like Granular Ferric Oxide (GFO) for aggressive phosphate removal or activated carbon for pulling out yellowing pigments and organic toxins—is standard practice for preventing nuisance algae blooms. However, traditional large media reactors are notoriously heavy and frustrating to maintain, often requiring you to disconnect tight plumbing lines, unbolt leaky thumb-screws, and drag a massive dripping cylinder over to a sink just to change out your carbon. The IC-GFO-150INT fully resolves this maintenance headache with its clever split-tier canister architecture.
Designed exclusively for internal, in-sump applications, this showcase-scale reactor features a standalone base that drops cleanly into your main filtration compartments, keeping your cabinet free of external flood risks. At the core of the 150INT is a removable inner cartridge. To change out your media, simply turn the top union cap and lift the self-contained inner canister straight out of the reactor column while leaving the heavy outer housing resting in your sump. This internal pod confines the media safely to its vessel, meaning you can easily dump old media, pour in new granules, and thoroughly rinse away fine black dust right at the sink before sliding it back into position. Driven by an included, high-output 49W EVO-3000 submersible feed pump that sits adjacent to the base, this comprehensive kit optimizes equipment space while delivering professional-grade water clarity with effortless upkeep.
Key Features
Hassle-Free Media Rinsing: The inner core cartridge acts as its own wash basket, keeping fine carbon or GFO grains completely contained while you rinse away transit dust under your sink tap.
Precise Fluidization Tracking: Ultra-clear outer acrylic walls give you a perfect view of your filter bed, letting you check for plumbing channels or adjust your flow rate to prevent tumbling GFO from grinding into dust.
Complete Out-of-the-Box Kit: Ships fully loaded with a matching high-performance submersible utility pump, an adjustable output control valve, and heavy-duty internal connecting plumbing lines.
(Note: This complete reactor assembly includes the internal reactor housing base, removable inner media canister, output gate valve, and IceCap EVO-3000 pump. Granular carbon and bulk GFO media are sold under separate product categories).

- Unbox your IC-GFO-150INT reactor kit. Twist the top cap assembly counter-clockwise to open the main body, and lift the massive inner clear canister cartridge out by its top rim handle.
- Remove the top sponge sheet divider from inside the inner canister. Pour in your chosen filtration media (such as activated carbon or GFO), place the foam layer back down to compress the media bed, and snap the canister top cap securely into place. Note: Depending on the media used, particularly GFO it is best to place it in a fine mesh bag to prevent the media from blowing out past the foam retainers.
- Take the packed inner canister to your sink and run cold water down through the center core pipe. Continue rinsing until the discharge water runs completely clear of dark carbon or iron dust.
- Lower the rinsed canister back down into the primary reactor body shell sitting inside your sump, ensuring it sits flat on the base alignment tracks. Re-seat the main top cap ring and twist it clockwise to seal the unit. Note: If this is the first time installing and using, we suggest that you place the whole reactor in a bucket of aquarium water and run it prior to placing in your sump.
- Use the short length of included tubing to connect the output nozzle of the EVO-1000 submersible feed pump directly to the lower intake port of the reactor base frame.
- Submerge the complete pump and reactor assembly fully into your sump filtration chamber. Open the integrated adjustment valve halfway, plug the pump into a wall outlet, and slowly turn the valve knob until your media reaches a gentle rolling fluidization.
Pro Tips:
- Dial in a Low, Gentle Tumble for GFO to Prevent it from Grinding into Dust. Granular Ferric Oxide (GFO) is quite brittle compared to activated carbon. If you push too much water through the reactor, the heavy iron granules will slam against each other violently, grinding themselves into a fine red dust that can bypass the internal filter sponges and cloud your display tank. When running GFO, adjust the built-in top output control valve down until only the very top surface of the media bed is gently simmering like boiling water. This gives you optimal chemical contact time while preserving the structure of the granules.
- Do Not Pack Carbon Too Tight; Aim for a Static, Non-Tumbling Packing Bed. Unlike GFO, which needs a light fluidizing movement to prevent it from solidifying into a solid brick, activated carbon should remain completely static inside the reactor. If carbon granules are allowed to tumble and rub against one another, they will quickly wear down and release fine black carbon dust into your tank water column. Use the internal sponge sheets to pack your carbon down firmly so it stays locked in place while the water passes through.
- Clean the Internal Sponges and Check the Pump Impeller Every 60 Days. Over months of continuous filtration work, fine organic mulm, bacterial slime, and calcium scales will naturally accumulate within the upper and lower foam filter discs inside the canister. Left unchecked, this buildup will restrict water flow and cause backpressure on your feed pump. Every second media change, take a few minutes to rinse the sponges thoroughly in hot tap water and pull the magnetic impeller out of your EVO-3000 pump to wipe it clean. This simple maintenance step keeps your flow rates consistent and significantly extends the lifespan of your pump.
