COR-15 Intelligent Return Pump (1500 GPH)

The COR-15 is a next-generation return pump engineered for aquarists who demand precision control and reliability. Delivering up to 1500 GPH, this intelligent pump connects directly to your Neptune Apex Controller via 1LINK—no external power supply needed. Its Vector Control BLDC motor runs whisper-quiet at under 50W, while IQ-Level Technology lets you fine-tune minimum and maximum flow rates to match your system's exact plumbing requirements. Monitor real-time flow, temperature, and power consumption through Apex Fusion, with automatic safety slowdown if temperatures rise. Multiple outlet adapters (¾", 1", and 1.25" options) ensure compatibility with standard reef tank plumbing. Designed for internal or external mounting, the COR-15 transforms return pump management into a fully automated, responsive component of your aquarium ecosystem. Requires an available 1LINK port on Apex A2 or A3 controllers.
