i just got a fluval fx5 for my fish only saltwater tank. My tank has an overflow on it that came attached to the tank (used to run a refugium when it was a reef tank). I was wondering how I can use that filter while still using the overflow so it looks nice. Is the best way to run the overflow into a sump and then run a hose from sump to filter to uv and then back out the overflow? or is there a better way? thanks
