Neptune Apex COR 15 Intelligent Return Pump (1500GPH)

Product details

Neptune Apex COR 15 Intelligent Return Pump (1500GPH) is an aquarium-rated, variable-speed brushless DC return pump designed to circulate your tank’s water smoothly and efficiently. Installed in your return plumbing, it helps move system water from the sump back to the display, supporting consistent filtration and overall flow. Because the COR uses an intelligent control interface, it can be managed in an Apex system for practical tuning of return flow to match your setup.

This pump is built to be quiet while providing strong circulation for its size, making it suitable for both performance-focused builds and everyday, low-noise aquarium setups. It comes bundled with the fittings and connection hardware commonly needed for aquarium return-line installations, so you can plan a clean return plumbing run with the included union and slip adapters.

Features:

• Variable-speed operation using a brushless, DC-driven centrifugal pump
• Designed for aquarium use with an emphasis on quiet operation and energy efficiency
• Intelligent control capability when used with an Apex system featuring an available 1LINK port
• Includes common return-plumbing fittings to help streamline installation across typical aquarium configurations
• Bundled 6-foot 1LINK cable to connect the driver to your Apex controller
