I am beginning to replace my current wavemaker with vortech's. I question is which would be better for my 120 gallon (24"x24"x48") with a bit of live rock and a mix of sps & lps. A couple of MP10 or MP40. Is the mp40 overkill? They can be turned down but if you use the MP40 and 1/2 speed why pay the extra price. The mp10 will pump more than 1500 gph and I now have a tunze 6100 which is 1600 gph and is too much no mater where you place or aim that powerhead. It either pounds all corals within 2 feet of the flow or creates sand storm if angled at the glass.
