Inline Hydor without can filter

[deejay kram]

Hello - New to this hobby (SW), and setting up a 75 gallon reef/fish. I would like to add the Hydor inline heater, but I am using a HOB refugium. Yes, I know, but this isn't about that...

My question is, has anyone simply added a pump to use with the Hydor? Seems simple enough, but your personal experiences would be of help. Seems a pump that needs a 5/8 fitting, and likely would be separate from the rest of the filtration system.

I really don't want to chance a heater in the refugium, and don't want it in the tank. So I was thinking a simple "closed loop" with an external pump and the Hydor heater?

Appreciate your feedback.

Ouch. I guess no one has tried this. I tried searching but found nothing. I'll just go ahead and try it anyway. Thanks for looking.
