Jon, as good as becketts are, { I use an MR3}, I would trade it anyday for a large Euroreef like one of the CS12 models, if I could afford one.
Newguy, for large tanks, pumps for the different skimmers come to about the same. A large beckett like mine, running on a Mak 4 but would work better on an Iwaki 70. Now thats a large pump, but to get the same results from a Euroreef, one of the double or better yet, triple pump models is requred.
A Sedra 5000 uses 55 watts, so its still 165 watts and three pumps to service/replace. I would guess the Sedra 9000 pumps use even more?
