Neptune Systems COR-15 Flow Chart

1500 Gallons Per Hour !

The COR-15’s powerful head-loss curve allows it to pump up to 1500 gallons per hour. To adjust the COR pumps output to your reef tank’s current plumbing size, each pump comes with a variety of alternative output connections. Although it is advised to use the biggest 1.25″ Union that is provided, using the other 0.75″ or 1.0″ adapters is completely OK.


Intelligent Tech

Every COR pump from Neptune Systems comes with IQ-Level technology since no two aquariums are the same. Set your tank’s plumbing’s minimum and maximum speed settings to the optimal flow rate. Don’t forget to adjust the minimum flow rate for the feed and in-tank flow modes as well.


Very Silent

The most recent Vector Control, BLDC motor technology is used in Neptune’s COR. Driving the COR pump in a method that is extremely energy-efficient, vibrating and noise-free, and uses less than 50W at maximum power.



KAlways be aware of the status of your pump. With all of the capabilities that COR pumps offer, you can keep an eye on the “heart” of your aquarium and make repairs before they break. Pumps’ internal parts are prone to calcium and other mineral build-up from saltwater aquariums, which might obstruct flow but, more critically, could harm the pump. You can monitor the pump’s internal temperature, power consumption, and flow rate using Neptune Fusion, and you can create alarms and alerts to notify you if anything deviates from the typical range. The COR will really slow down until temperatures return to a safe level if the pump’s temperature rises to hazardous levels. giving you time to react and maintain the pump.
