I am interested in putting a Red Sea Reefmat 250 in my Red Sea Reefer 250 V3 sump. All the sump modifications on the Red Sea website eliminate the refugium chamber. From what I can tell the Reefmat 250 should fit with modifications to the overflow chamber and the filter sock chamber without eliminating the refugium chamber. I am using the refugium as a refugium and would like to keep it intact if possible. I ask Red Sea and they were no help. Has anyone tried this?
