flow questions

I don`t think you want to go over 5x your display volume going through the sump per hour. As mentionned before it can cause problems. The bulk of movement for SPSs should be made by powerheads. As mentionned before 50x is a common guideline, but it's just that, a guideline. Placement of corals and orientation of flow is pretty important too

You can push a lot through a sump, I had 2000gph (now lowered to 1000gph) with my 75g sump, just need to be prepared (bubble towers, filter socks, foam blocks).

For the OP, I'd just keep the return you have now, give your Koralia's a try. If looking like you need/want more flow, add another or switch to higher flow PH (Tunze Stream).

The pump he has now is rated for 500gph at 1' of head.. http://www.lgpc.com/Product/ItemDeta...ProductID=1512 ...at 3' of head he will barely be moving any water

While that's not a pump, (thought he meant 500gph at head).

Mytank, take a look on RC head loss calculator to help select a return pump.
