IceCap Gyre 2K Pump Only The IceCap Gyre 2K Pump Only is a pump-only version of the IceCap 2K gyre flow pump for aquariums from 20 to 90+ gallons. It is intended for aquarists who already use or plan to use a compatible HYDROS WaveEngine, WaveEngine LE, or IceCap Gyre controller setup and want the 2K pump body without purchasing a complete controller bundle. IceCap 2K Pump Only Overview The 2K Gyre Pump Only gives reef keepers and aquarium hobbyists the same broad crossflow pump hardware used in the controller kits, but in a format meant for controller-based systems. This is useful when adding a second IceCap Gyre pump to an existing controller, replacing a pump body, or building a cleaner HYDROS-controlled flow system where multiple pumps are managed from a central platform. Because gyre pumps create a sheet of water movement across the aquarium, the 2K can help move water through rock structures, improve oxygen exchange, keep detritus suspended, and reduce stagnant zones that are common with narrow-output pumps. The lower 2,000 GPH maximum flow makes this model a better match for smaller and medium aquariums than the larger 4K model when space and livestock tolerance are more limited. 2K Pump Only Features Pump-only configuration: Designed for systems that already have compatible IceCap or HYDROS pump control hardware. Gyre crossflow pattern: Produces broad linear circulation that helps move water through the full aquarium instead of only one narrow stream. 2,000 GPH maximum flow: Strong enough for many nano and medium reef systems while remaining more manageable than larger high-output gyres. Direct Drive compatible: Can be used with compatible HYDROS WaveEngine systems when the proper IceCap Gyre adapter is used. Horizontal or vertical mounting: Flexible orientation allows the pump to be positioned around different aquascapes and flow goals. Waterproof magnet mount: Secure magnetic mounting supports glass or acrylic aquariums up to 1/2" thick. Twin directional cages: Adjustable flow cages help shape the direction of water movement across the tank. Two propeller colour sets: Orange and black propellers are included for setup flexibility and visual preference. Compact linear body: The slim gyre format can be mounted close to the surface and kept less obtrusive than many bulky circulation pumps. IceCap Gyre 2K Pump Only Specifications Product type: Pump-only gyre aquarium circulation pump Recommended aquarium range: 20-90+ gallons Maximum flow: 2,000 gallons per hour Minimum flow: 739 gallons per hour Power consumption: 8-25 watts Pump dimensions: 8.78" L x 2.83" W x 1.5" H Pump weight: 457g / 16.1 oz Cable length: 6 ft Maximum aquarium thickness: Up to 1/2" Aquarium material compatibility: Glass or acrylic Controller compatibility: Compatible IceCap Gyre controller or HYDROS WaveEngine system with required adapter Application: Reef, saltwater, and high-flow freshwater aquarium circulation 2K Pump Only Compatibility Notes Controller requirements matter: The IceCap Gyre 2K Pump Only is not the same as a full controller kit. It is best for users who already have compatible control equipment or are building a HYDROS WaveEngine-based flow system. When connecting to a WaveEngine or WaveEngine LE, the appropriate HYDROS IceCap Gyre pump adapter is required and is not included with the pump-only item. Choose the right pump size: The 2K model is generally the better choice for smaller reef systems, narrower aquariums, and tanks where the 4K model may be too aggressive. Use lower settings for new coral additions, soft corals, fine sand beds, and livestock that prefer moderate flow. Official IceCap Gyre Setup Video Setting Up the IceCap 2K Pump Only Connect the pump to the compatible controller or HYDROS system using the correct connection method, mount the pump securely on compatible glass or acrylic, and set conservative speed limits before running strong wave patterns. Test the flow path across the full aquarium and reposition the pump if water movement is too direct, too weak behind rockwork, or disruptive to the sand bed. Clean the rotor assembly, cages, and magnetic mount during routine maintenance to maintain reliable performance.
