NEW Tank build starts here

[DAVE]

You want your return pump to match your skimmer output.

There is no point in putting 10x the flow through your sump if your skimmer isn't going to be able to handle the water volume that is moving through your sump.

Since you are planning on an LPS dominant system with a few SPS and you are already going to be running MP10's then there is no need to get crazy with your return pump, just have it match or be a little less then your skimmer pump.
