So id like to add a 20 Gallon Refugium to my 40 gallon sump. Right now there's really just enough room for a skimmer and some live rock in the initial Chamber where the water drains in from the DT. My question is should I cut into the main drain and have a smaller pipe drain into the added refugium or just add a small pump and have that pump water into the added 20 gallon tank then have it just drain right back into the sump?
