Yep its for the big system. I was going to go with a mag 18 for a return, but then i would need to plug up the bulkheads in the sump. I figure about 4-5 feet vertical and maybe 2 feet horizontal for head loss. I was thinking the snapper, but was afraid it would be cut back to much with a manifold. The sump has a bulkhead very near or the same as the inlet size on the dart/snapper so figured it would be easy, plus i like the energy ratings of the snapper. So many choices....but for 171 vs 234 at jl it mkes it even harder to decide. I've heard good things about both pumps...but i think with the head loss the mag would be underpowered. I have also decided to not really utilize the baffles in my sump and to fill the water over them. I think to much of the sump is wsted withthe heaght of the baffles that are in it now. I have to work boxing day
Now i hafta run out and get some epoxy to finish up my stand. Good christmas project
EDIT: I cannot spell, I aplogize but i don't feel much like fixing the inumerable errors...
