Well, the 1200s stink for efficiency based on their stock flow specs...the 1200 is 295gph for 24 watts, and the 900 is something like 8 or 9watts and can push 230gph. The 1200 is designed with a much higher head-pressure however...to be used for skimmers. top-offs, and some sump returns where the lower wattage ones would begin to choke.
At that, with the stream mods, the 1200 has loads of torque that it can cash in on with that extra 16 watts...like by running dual 1.75" props. So I guess what I am trying to say is that the 1200 might still be an option, as a way of only having to use one unit to make 3000gph and not two. Also consider that the wattages on these prop modded units seems to go down 20%.
While the MJ1200 might consume 3x the wattage, it might also produce 3x the flow, and my thoughts were to minimize the number of pumps needed when I suggested 1200s...but 900s might be fine as well.
Maybe ChemE and I need to come up with a scientific way to test these stream pumps.
