how many times a hour should the water go through the sump?

I have a DIY Recirc skimmer on ly 150, return pump is a Little Giant 4 Mqdx, like 1100GPH or something at 0 head. I was running about 6-700GPH through sump. I throttled the return back, and added a N/P pellet reactor T'd off the return pump. Now, I am about 300GPH i would say, and my skimmer works WAY better. I'm pulling more tea than before, and consistent. No adjustments were made to skimmer, or water height. Just flow.....
Make your own conclusions from that
