Neptune Systems COR-20 Intelligent Return Pump

RUNS STANDALONE – NO APEX NECESSARY!
Thats right, the COR-20 will run completely standalone OR connected to ANY Apex System via its AquaBus port. If you dont yet have an Apex, dont worry, down the road when you get one, youll open the door to many more features (like mobile notifications).

UP TO 2000 GPH (7500 LPH)
When properly plumbed, one COR-20 provides enough flow for aquariums up to 180 gallons. For larger systems, use two COR-20 for redundancy and disaster prevention.

The COR pumps are compatible with all Apex systems including: Apex, Apex Classic, Apex Lite, and Apex Jr. Simply connect the COR driver to the Apex via any available AquaBus port.

FOR INTERNAL OR EXTERNAL APPLICATIONS
With its included fittings, the COR-20 can be plumbed to work either externally, or submerged in a sump.
