No idea on 300g manufacturer, dimensions 96" x 30" x 24" with center 12" overflow single 2" drain and two 1.5" returns. I'm working on building a stand for it and searching for a 125g or larger tank for cheep to make into a sump.same tank that i have?? marineland made 300 deep dimension?? if so i would suggest follow the sump i have design in the 2nd page of this thread.. and to increase flow i would use the 4 holes for drain use...
