I run the same frag tank and my flow comes from an mp10 and a nano korila. The mp would be more than enough on its own, I just use the nano aimed directly über the frag racks to keep and thing from settling.
Thanks for all the info. This tank will PRIMARILY be holding my chalice collection as well as some high end frags of things like zoo's and some SPS. I will be setup and run like a reef tank in that it will have sand and a few small fish in it but the majority of the system will need that flow I think. I guess I can try it with the MP10 because there will not be a lot of rock work. If necessary I will just sell the MP10WES with the extra wetside and purchase 2 MP10's with the proceeds. With those 2 I should have more than enough flow.
