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 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!
