i will have a 20 set up soon with a 20 sump/fuge combo,, do you think a mag 5 will be enough to get the water back up to the main tank about 40 inches above the sump?
cool , acording to the chart on that page at a 4ft head i would still have 300 gph minus a little for a couple of elbows so i should be fine, thanks for the link
