Hey all, I have a WB Marine X 110.4 (80G display, 26G sump) on the way. I was looking at the Vectra S2 (1400GPH), but my LFS recommended the M2 (2000 GPH) as the added flow would be helpful once I account for all the vertical plumbing that is needed to bring the water from sump to output nozzle. What are your thoughts on that? Would you recommend another pump? Thanks!
