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 to be intelligent, energy-efficient, unbelievably quiet, and incredibly powerful for its size.
The COR-15 and COR-20 use a relatively new connection standard for the Apex called 1LINK. The 1LINK port provides up to 50w of power as well as the control signal to connected devices. The advantage for devices like the COR-15 and COR-20 is that no additional power supplies are necessary. These 1LINK ports are present on the recently released Energy Bar 832 as well as on a separate 1LINK module. All COR pump models are fully compatible with every Apex system on the market, but can function without an Axe system.
The COR-15 and COR-20 put out great flow while at the same time being super-stingy on power making it friendly to you wallet and the environment! Be sure to plumb the COR-15 or COR-20 using the largest diameter pipe possible to get the best performance. We recommend at least 1.25".
The COR was built from the ground up with Apex controllability in mind. Control your pump output percentage, get real-time operational feedback from the pump, integrate it into complex feed routines, and monitor the status of the pump from anywhere in the world via Apex Fusion.
With Whisper-Drive technology, this pump is both extremely energy efficient and remarkably quiet, plus with obstruction detection, you'll receive an alert on your mobile phone if snails, filter pads, or other foreign objects find their way into your pump.
The pump driver is continually monitoring the internal temperature of the COR pump motor. If it reaches an unsafe level, the driver will slow the pump down just enough to bring the temperature into an acceptable range while also providing you a notification. Some pumps shut off completely when they have a temperature issue, but the COR slows down so your tank will continue to circulate — giving you time to address the problem.
Set the output level you desire for your aquarium and overflow capability and the COR will memorize that and make it your “100%” for your aquarium. If power should go off, when it restarts it will always return to that memorized setting. Also, during feed modes, your water will not completely back-siphon. This prevents the burping and bubbling that normally occurs when a pump powers back up.
With some simple configuration in Apex Fusion you can set a Feed Mode that will slow the pump to any level you choose. You can even have other tank operations sequence with this feed mode and the time interval of the Feed Mode can be customized as well. The buttons on the COR driver also function as an easy to use feed button.
Requires: Plumbing fittings, hose, pipe, basic plumbing knowledge, and any Apex with an available 1LINK port.
Includes: COR Pump, COR-15 or COR-20 Pump Driver, PVC Union, Slip fitting, 1LINK Cable.
The COR comes complete with all the fittings necessary for most aquarium configurations (0.75" output, 1.0" input). But we’ve also included a 1.25” union for the output so you can connect the pump in a manner that will result in the least amount of head loss. Plumb your main return-line in 1.25? and get the full potential of the COR pump – as much as 50% or more flow!
Connect the plumbing, plug the COR into its driver and plug it in a 1LINK port. With just a few button presses you will be able to set the pump flow rate and feed modes. A set up task will take you step by step through the entire install process.
