Quick question. I have a 120 gallon 48x24x24 tank I'm setting up as a fowlr. It has a dual built in overflow going to a 40 gallon sump. I have a mag drive 7 and a mag drive 18. Which of these two pumps would be better for my return. The 7 would give me 420 gph at the return height. The 18 would give me 1200 gph. Thanks for the help.
