A high turn over is accepted for SPS but sort of two views on flow through the sump. There's from match your return pump to your GPH rating of the skimmer to having the return contributing a significant amount of the display turnover. I'm of the latter but having a high flow through the sump can add problems such as noise and microbubbles.
Idea though is get a good overall flow, not blasting it all out of one or two nozzles. Always liked this thread for an idea of what others are doing flow-wise.

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).

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