Sump Flow
This should open up a big can of worms. But here goes. 75 Gal tank with 30 gal sump/refugium @ 5' of head. What size/type of pump/GPH would you go with and why. I plan on having a line off the overflow to feed the refugium portion, so I will be able to control the water flow into it.
Cheers,
Al
