Can somebody please point me in the right direction? I am trying to decide between the Mag 7 and Mag 9.5. I am using a Eshopps 800 gallon overflow. The sump is in a different room so I have a lot of flexibility with head pressure depending on how far off the floor I bring the sump. The only thing I can't control is the 17' of vertical distance and four 90 degree turns. Will the 9.5 be too much or will the 7 work? According to the calculators online, the 7 would be putting out 468 GPH after head loss. The 9.5 would be putting out 726 GPH which is kind of close to my 800 GPH maximum.
