Sump circulation question

I just spent a week putting the sumps together due to the fact that I am building a much larger display tank soon and I wanted to get all the sump work done first. So I don't want to take one out now, LOL

I can take a couple of lines off of my return manifold to act as power heads if I need to. I just don't know if that is a good thing or not. That is what I am trying to determine.

I think overall a person wants as much settling area as possible for sediment to settle and for any bubbles to dissipate. Increasing flow in the sump would stir up the sediment. I do have a 100-micron filter sock on my inlet but there is still always some debris in the bottom of the sump.

Basically I am wondering if there is any fear of the water not oxygenating enough, going stagnant, if any of the mineral levels will fluctuate or build in less active areas. And will ALL the water in the sumps circulate throught the system or will some of the water actually sit in pools and never leave the sump, etc.
