Who is Using a Refugium for Nutrient Control?

[hillegom]

You have water comming into the sump already by gravity from the overflow.
Why don't you T off somewhere with a valve and use plain old gravity to feed your refugium and then overflow to sump?
Adding another pump when gravity will work, to me, is overkill.
