(1) MP40 or (2) MP10's

Should I get (1) mp40 or (2) MP10's for my 90g?

My gut says that you will need two of which ever you pick. I get away with one MP10 in my 3 foot tank, but I would like to have a second.

You could start with two Mp10's and if it isn't enough you can always sell them quickly and easly on here and replace them with MP40's.

Mp40

I by no means am a bigtime expert, but I want to think the intermittent pulsing flow of one MP40 with perhaps a SCWD on your return (If you use a sump) and a pump or two tucked away in the rock would be more than plenty. Of course it depends on many things, but that seems like a good starting point.

Or even 1 MP40 counterpulsing with an MP10 on the opposite side? Seems like the diversity of flow strength and direction would be a nice "natural" touch for the corals.

I would go with the MP40. I think that you would really have to crank up the MP10's for a 90 gal tank. They would be working harder, hotter, noisier,and probably ware quicker. The down side with one MP 40 is that you cant get the cool back and forth flow. With 2 Vortech's, you can get some really cool flow patterns. Tough choice.
I have an MP40 and an MP10 in my 75 and they work great together, and I didn't have to drop a ton on two MP40's.

ok thanks guys.. I think I will get (1) MP40 for the time being and then maybe add another down the road... but not too far down that road
