Neptune Systems COR return pump

For the past few months, I’ve been lucky enough to be a Neptune Systems insider and testing the Neptune Systems COR20 return pump on my reef aquarium. I’ve run it in standalone mode as well as programmed into my Neptune Systems Apex Classic.

So far, I love it. What do I love about it?

  • Quiet
  • Energy efficient as it’s a DC pump
  • You can ramp speeds throughout the day (I slow it down at night to make things calmer in the reef tank
  • Alarms, as an example, detects if it’s dry and no water and will text/email me

Being a Neptune Insider I had to update my firmware on my Neptune Systems Apex Classic to a version that isn’t released yet. However, the process was the same for any firmware update, super easy.

Installing and mounting wasn’t that hard and to save time I had the guy that helps maintain my reef install it.

Below are a few pics of the unit:
