Your return pump is by far the most important piece of equipment on your aquarium. It circulates the water, which is basically the life-blood of a tank. Creating a great aquarium is just like building a great body – it all starts at the core – and this is precisely how our pump got its name!

The COR is a variable speed, brushless, DC-driven centrifugal water pump designed specifically for aquariums. It is intelligent, energy-efficient, unbelievably quiet, and incredibly powerful for its size.

Highlights of the COR-20:

  • Runs standalone – no APEX necessary!
  • Up to 2000 GPH (7500 LPH)
  • Compatible with all APEX systems
  • For internal (submerged) or external applications
  • IQ-Level sets the proper minimum and maximum flow rates for your aquarium
  • Includes oversized 1.25″ union
  • Energy-efficient – uses less than 90 watts of power!
  • Incredibly quiet!

Editor’s Note: According to public commentary from online retailer Marine Depot, “COR pumps begin shipping to retailers…the first week in January [2018], but quantities are limited. But early adopters who pre-order should have their pumps delivered in a few short weeks, so that is good news! The next round of pumps will ship in March.”
