The IceCap FP Series are controllable DC flow pumps that keep water moving in freshwater and saltwater aquariums. A directional propeller design pushes a broad, gentle stream that clears dead spots, boosts surface gas exchange, and carries food and nutrients to corals and filter feeders. Each pump runs on a variable-speed controller so you can dial the flow to the tank instead of being stuck at one fixed speed. Pair one with your saltwater or freshwater setup. Why This Pump Variable-speed DC motor with an included controller, tune the flow from a soft ripple to full output Directional propeller pushes a wide, even stream rather than a narrow jet Works in both freshwater and saltwater tanks Energy efficient, from just 10 watts on the FP-60 Magnet mount holds on glass or acrylic and aims where you need flow Quiet running for display tanks Choose Your Model Model Max Flow Power Best For FP-60 790 GPH 10 W Nano and small tanks up to about 50 gallons FP-100 1,585 GPH 20 W Medium tanks, roughly 50 to 120 gallons FP-200 4,755 GPH 35 W Large tanks and long displays, 120 gallons and up Flow needs vary by tank shape and livestock. Reef tanks usually want higher turnover than fish-only or planted tanks. How It Works Mount the pump with the magnet holder and point the nozzle to aim the flow Connect the controller and set the speed, many models offer steady or pulsing modes Run more than one pump on opposite walls for a natural, random flow pattern in larger tanks Rinse the propeller and housing during routine maintenance to keep output strong Specifications Brand IceCap Type Controllable DC flow pump / wavemaker Water Freshwater and saltwater Control Variable-speed controller included Mounting Magnet holder FP-200 dimensions 4 x 3.3 x 3.3 inches Recommended Pairings Run a second FP pump for balanced flow in reef tanks Add a heater and reliable filtration for a complete life-support setup Browse more aquarium equipment for your build FAQ Does it come with a controller? Yes. Each FP pump includes its variable-speed controller so you can adjust the flow. Can I use it in a freshwater tank? Yes. The FP series works in both freshwater and saltwater aquariums. How many should I run? One pump is plenty for small tanks. Larger or reef tanks often use two or more on opposite walls for random flow. Which model do I need? Match the max flow to your tank size using the comparison table above, and size up if you keep flow-loving corals.
