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.
