Hi Roger, I have a 200g (96Lx24wx20h) mixed reef LPS/SPS tank with 4 equal spaced return lines pushing roughly 900gph per line. I currently have a 6155 on the left side of the tank and planning on getting a 6105 for the right side of the tank. How would you recommend placement of the pumps and would this be enough flow? They will be on individual 7091 single controllers until I can get a multicontroller. Do you think I would need to use the wide flow kit for the 6105? Thanks in advance.
