Description: INTELLIGENT, QUIET, ENERGY EFFICIENTYour 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. NO APEX NECESSARY! The COR-20 does not require an Apex to operate. If you do not yet have an Apex don’t worry, much of its functionality is available from the button and LED interface on its driver. However, connect it to your Apex and it becomes the most intelligent and feature-rich aquarium pump on the market today! COMPATIBLE WITH EVERY APEX All COR pump models are fully compatible with every Apex system on the market. Simply connect the COR pump driver to any available AquaBus connection on your Apex system and then run the setup task in Apex Fusion. It’s that easy! GREAT FLOW TO POWER RATIO The COR-20 puts 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-20 using the largest diameter pipe possible to get the best performance. We recommend at least 1.25″ (3.18cm) ADVANCED CONTROLABILITY While an Apex connection is not required, the COR was built from the ground up with Apex controllability in mind. Connect the COR to the Apex and 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. EASY INSTALLATION Connect the plumbing, plug the COR into its driver and plug it in to an outlet. With just a few button presses you will be able to set the pump flow rate and feed modes. If you connect it to an Apex, a set up task will take you step by step through the entire install process. WHISPER-DRIVE TECHNOLOGY The COR uses the latest in Vector Control, BLDC motor technology. This drives the COR pump in a way that is both energy efficient as well as nearly vibration and noise free. Go ahead, we challenge you to find a quieter pump! OBSTRUCTION DETECTION Snails, filter pads, or other foreign objects often find their way into a pump. Should the intake to your COR or any of your plumbing become significantly obstructed, the COR will alert you by flashing the LED on the driver. When the COR is connected to an Apex and the internet, it will send an alert to your mobile device as well. INTERNAL TEMPERATURE MONITORING 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. IQ-LEVEL 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. FEED MODE With a few button presses (standalone mode) or some simple configuration in Apex Fusion, you can set a Feed Mode that will slow the pump to any level you choose. When connected to an Apex, 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. When connected to an Apex, the buttons on the COR driver also function as an easy to use feed button. The COR comes complete with all the fittings necessary for most aquarium configurations (0.75″(1.91cm) output, 1.0″(2.54cm) input). But we’ve also included a 1.25”(3.18cm) 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″(3.18cm) and get the full potential of the COR pump – as much as 50% or more flow! Real-time Operational Feedback: Monitor the pump's internal temperature, wattage draw, and flow rate directly through Apex Fusion. This allows you to catch potential issues (like an obstruction) before they become critical.Alerts and Notifications: Receive alerts to your phone or email if the pump encounters an issue (e.g., obstruction, overheating, power failure).Obstruction Detection: The pump can sense if something is blocking its impeller (like a snail or debris) and will alert you, and in some cases, slow down to prevent damage.Internal Temperature Monitoring: If the pump starts to overheat, the Apex can automatically reduce its speed to bring the temperature down, preventing permanent damage while keeping water circulating.Whisper-Drive Technology: Utilizes advanced BLDC (Brushless DC) motor technology with vector control, making the COR-15 incredibly quiet and virtually vibration-free. This is a significant advantage, especially for aquariums in living spaces. Energy Efficiency: Despite its powerful flow, the COR-15 is highly energy-efficient, consuming less than 50W at full power. No Bulky Power Brick: It connects directly to a 1Link port on an Apex EnergyBar 832 or 1Link module, drawing both power and control signals through a single cable. This simplifies wiring and reduces clutter. Internal or External Use: The COR-15 can be used submersed in your sump or externally (out-of-sump) as a closed-loop or reactor feed pump. Versatile Plumbing: Comes with various output fittings (0.75", 1.0", and an oversized 1.25" union) to accommodate different plumbing sizes, minimizing head loss and maximizing flow. Reliable Build: Designed for durability in saltwater environments, though regular maintenance (cleaning) is still essential to prevent calcium build-up. Specifications : Max Flow Rate: Up to 1500 GPH (gallons per hour) / 5700 LPH (liters per hour)Max Head Pressure: Approximately 4 meters (around 13 feet)Power Consumption: Less than 50W at full powerDimensions (Pump): Approximately 9.8cm (W) x 12.3cm (H) x 15.8cm (D)
