thatoneazn Posted December 10, 2009 Share Posted December 10, 2009 Hey guys, I am looking to acquire a 30 gallon cube, and i already have a 15 gallon tank. Is that large enough to be the sump? Also, i am new to sumps, have had a nano tank most of my life, i understand that gravity feeds the sump, and the pump pushes the water back up. This is a problem, what happens if there is a power outage and i am not home. How do i prevent my sump overflowing my floor? Link to comment
