INTRODUCTION
Congratulations on your purchase of the Neptune Systems APEX COR pump!
This Guide is for use by persons who will be using their COR pump in
conjunction with a Neptune Systems APEX controller system. If you will be
using the COR-20 without a Neptune Systems APEX system, refer to the
COR-20 Standalone User Guide found on the Documentation page on the
The COR-15 and COR-20 pumps are flow-optimized, energy-efficient variable-speed DC
pumps which are ideal for use as a return pump, closed loop pump, or reactor manifold
pump in saltwater and freshwater aquariums. The COR-series pumps were designed
from the ground up to be tightly integrated with the Neptune Systems APEX family of
aquarium controllers for ease of use and advanced control, however the COR-20 CAN be
operated WITHOUT connecting it to an APEX.
A Neptune Systems APEX controller with a free 1LINK port (provided by either the 1LINK
module or Energy Bar 832) is required to utilize the COR-15; it cannot function as a
standalone pump.
The COR pumps systems are fully compatible with all APEX controller models, including
the APEX (2016), APEX Classic, APEX Gold, APEX Jr, and APEX Lite. The COR is not
compatible with pre-APEX generations of Neptune Systems controllers such as the
AquaController 3 or ACjr.
