I have an Oceanic 150 trickle filter that I was thinking about gutting and using as a sump/refugium. It's about 32" x 12" x 18" and works out to right around 30 gallons. It uses an external pump so I could make the return section a little smaller. Does this sound feasible? I know bigger is better when it comes to sumps but it's a nice tank and I don't know what else to do with it.
