IceCap Controllable DC Media Reactor - Medium The IceCap Controllable DC Media Reactor - Medium is a mid-size controllable aquarium media reactor for freshwater and marine systems up to 120 gallons. With approximately 345mL media capacity, a DC-400 adjustable feed pump, removable twin-chamber canister, and compact 2.7" x 2.7" footprint, it offers flexible filtration control for GFO, activated carbon, biopellets, and other compatible media. Medium IceCap DC Media Reactor Overview The Medium IceCap Controllable DC Media Reactor is the balanced option in the series, offering more capacity and flow than the small model while staying compact enough for many sumps and filtration compartments. Its included DC-400 pump provides five controllable power modes so users can adjust water movement through the media instead of relying on a fixed-flow setup. This makes the reactor useful for mixed reef tanks, fish-only saltwater aquariums, freshwater systems, and all-in-one aquariums where nutrient control and water polishing need to be tuned. The removable twin-chamber cartridge also makes media service cleaner because the cartridge can be lifted out rather than removing the entire reactor body from the filtration area. Medium DC Reactor Features Mid-size filtration capacity: Approx. 345mL media capacity supports aquariums up to 120 gallons. Controllable 12V DC pump: The included DC-400 feed pump provides adjustable flow for different media requirements. Five power modes: Pump speed can be changed to dial in gentle tumbling, steady contact, or higher flow depending on the media used. Removable twin-chamber canister: Upper and lower chambers allow flexible media placement and easier service. Compact reactor footprint: The 2.7" x 2.7" footprint fits many sump layouts and larger all-in-one rear chambers. Media change convenience: The media canister removes from the reactor body, simplifying refills and cleaning. Freshwater and marine compatible: Designed for aquarium use with GFO, biopellets, activated carbon, and compatible filtration media. Clear acrylic construction: Allows visual inspection of media movement, flow, and debris buildup. IceCap Controllable DC Media Reactor - Medium Specifications Product type: Controllable aquarium media reactor Part number: IC-GFO-60P Recommended aquarium size: Up to 120 gallons Dimensions: 2.7" L x 2.7" W x 14" H Body size: 2.4" Maximum media capacity: Approx. 345mL Pump: DC-400 Pump power: 6W at 12V Flow range: Approx. 120-400 L/H Installation: Sump or all-in-one filter compartment Application: GFO, biopellets, activated carbon, and compatible filter media Medium Media Reactor Compatibility Notes Choose media and flow carefully: GFO generally needs gentle movement, activated carbon usually benefits from controlled steady flow, and biopellets often require more active motion. Follow the media manufacturer's instructions and adjust the controller gradually to avoid grinding media, releasing fines, or restricting flow. Protect electrical components: The pump runs in the aquarium system, but the controller and power supply must stay dry. Use drip loops, keep cords organized, and mount the controller where it is accessible for flow changes but protected from splashes and salt creep. Setting Up the Medium IceCap DC Media Reactor Install the feed pump, connect the inline controller and power supply, and load the lower media chamber with rinsed media. Use the included sponge below and above the media as needed, then place floss or a secondary media in the upper chamber when appropriate. Place the reactor in the sump or AIO compartment, start at low power, and adjust flow only after observing the media movement and water clarity.
