Requires IceCap Dual Pump WiFi Controller

IceCap Gyre Flow Pumps are compatible with the Dual Pump WiFi Controller and can easily increase the flow in your tank with the addition of a second IceCap Flow Pump to your existing 2K or 4K Gyre setup. You can use any combination of Flow Pumps you like, meaning you can add a 2K Flow Pump to your 4K setup, or vice versa. This allows for additional customizability to meet the flow needs of your tank. 


New IceCap Gyre pumps bring powerful, signature Gyre crossflow and controllability at a value-orientd price point. Using officially licensed technology from Maxspect, the IceCap Gyre pumps generate a "sheet" of water across your tank, virtually eliminating any dead spots with improved overall water circulation. Compared to other traditional propeller style powerheads, the Gyre produces an even, linear flow that can reach across longer tanks without creating direct hot spots of flow. 


Wavemakers excel in making waves. While waves are spectacular to watch in motion, they are moving the majority of the water vertically up and down, with relatively low horizontal movement, especially near the bottom of the aquarium. On the other hand, gyre generating pumps excel in moving the sheer flow of water from one side of the aquarium to the other. The flow of water is so strong that it will bounce back from the opposite side to achieve full circulation within an aquarium, i.e., generating "gyre flow."

Product Questions

Can this pump be used with the Neptune Apex Pro?
Question by: Timothy Potter on Apr 27, 2023, 12:44 PM
Thanks for reaching out to us! This pump does require the IceCap Dual Pump WiFi Controller which can then be connected to the Apex via the 0-10V port.

Is the gyre 4k pump compatible with the 3k controller?
Please and thank you

Hello, thank you for your question. Only the 4k Gyre and 2k Gyre can be connected on the same controller. Happy reef keeping.
