Take your aquarium circulation to its peak with the Neptune Systems COR-20 Intelligent Return Pump. Upgraded with expanded capacity and massive operational flexibility compared to its sister model, this powerhouse pushes up to 2,000 Gallons per Hour (GPH) while utilizing a highly efficient 24V brushless DC motor. Whether you have a fully automated system or prefer a standalone setup, the COR-20 is built to run flawlessly with or without an Apex controller.
📐 Quick Specs
Maximum Flow Rate: 2,000 GPH (7,500 L/H)
Maximum Head Height: 21 Feet
Power & Connection: Wall-powered via an included 100W independent power supply; communicates with Apex via standard AquaBus
Energy Consumption: Max 90 Watts at full power
Plumbing Sizes: 1.25" Slip Input / 1" Slip Output (Includes an oversized 1.25" slip PVC union to maximize flow and reduce head loss)
Application: 100% safe for internal (submerged) or external plumbing applications
🌟 Key Benefits
No Apex Required: Equipped with an intelligent, standalone driver interface. You can set custom flow rates, program feed modes, and monitor your system directly from the hardware buttons without buying a controller first.
True Standalone Flexibility: Unlike the COR-15 (which must draw power directly from a 1LINK module or Energy Bar 832), the COR-20 uses its own dedicated power brick. This provides ultimate installation independence and leaves your Apex module ports open for other accessories.
Smart IQ-Level Customization: Features proprietary software that memorizes the ideal minimum and maximum flow parameters tailored to your plumbing. This prevents sump overflows and fine-tunes your water line.
Anti-Siphon Trickle Feed: During active feeding routines, the pump intelligently drops down to a gentle trickle rather than shutting down completely. This keeps water moving to prevent back-siphoning, bubbling, and the annoying "burping" sounds when ramping back up.
Obstruction & Thermal Safety: Features internal safety monitors that flash the driver LED if a snail or loose filter pad blocks your plumbing intake. If connected to an Apex via AquaBus, it will push instant push notifications directly to your smartphone.
