IceCap Gyre 4K Pump Only The IceCap Gyre 4K Pump Only is the pump-only version of the high-output IceCap 4K gyre flow pump for aquariums from 25 to 150+ gallons. It is designed for aquarists adding a 4K pump to an existing compatible IceCap or HYDROS-controlled flow system, or replacing a pump body without purchasing a full controller bundle. IceCap 4K Pump Only Overview The 4K Gyre Pump Only provides the larger IceCap gyre pump hardware for systems that already have the required pump control equipment. Its 4,000 GPH maximum output is intended for larger aquariums that need strong horizontal circulation, improved surface movement, better detritus suspension, or wider flow coverage through reef structures and open swimming areas. Because this is a pump-only item, it is especially useful for expanding a dual-pump WaveEngine or WaveEngine LE installation, replacing an existing 4K pump, or adding more directional flow control to a system already built around the HYDROS platform. The pump-only format avoids buying another full controller package when the control system is already in place. 4K Pump Only Features Pump-only configuration: Intended for users with compatible IceCap Gyre or HYDROS control hardware already available. 4,000 GPH maximum flow: Provides stronger circulation for larger aquariums, long displays, and higher-flow reef systems. Crossflow gyre movement: Helps move water in a broad sheet across the aquarium to reduce dead spots and improve circulation. Direct Drive compatible: Can connect to compatible HYDROS WaveEngine systems when used with the required IceCap Gyre adapter. Horizontal or vertical mounting: The pump can be oriented to suit aquascape layout, surface agitation needs, and coral placement. Waterproof magnet mounts: Secure mounting works on compatible glass or acrylic aquariums up to 5/8" thick. Twin directional flow cages: Adjustable cages allow the flow output to be shaped for different aquarium zones. Two propeller colour sets: Includes orange and black propellers for setup flexibility and visual preference. Discreet linear design: The longer low-profile body can be mounted near the surface for strong circulation while staying relatively clean-looking in the display.

When connecting this pump to a HYDROS WaveEngine or WaveEngine LE, the appropriate HYDROS IceCap Gyre WaveEngine pump adapter is required and is not included with the pump-only item. Size for the aquarium carefully: The 4K is powerful and should be used where its output can be managed properly. Large reef tanks, long aquariums, and SPS systems may benefit from the stronger flow, while smaller tanks, delicate livestock, loose sand, or low-flow corals may need the lower-speed range or the smaller 2K pump instead. Official IceCap Gyre Setup Video Setting Up the IceCap 4K Pump Only Connect the pump to the compatible controller or HYDROS system using the correct adapter and connection method, mount it securely on compatible aquarium glass or acrylic, and begin with conservative speed limits. Observe the aquarium's circulation pattern, livestock response, and sand movement before increasing output. During maintenance, remove buildup from the cages, rotors, propellers, and magnet mount to help preserve strong flow and quiet operation.
