Sump circulation question

[fencer]

Sounds like plenty of flow. If it is 1000 gph then you are changiing the main tank volume about 20x an hour. You probably could take out one of those sumps too. You might want to put a powerhead in each of those sumps justto circ the water around

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.

You'll be getting aeration by the skimmer and water going over the overflows.

Thanks, that is what I figured too.

I think main consern is water flow in the display tank :30 times or more for SPS is minimum, ( i am at 90 times turn over rate in the display tank, not counting the WaveBox and very little flow in the sump)
In the sump if you are circulating you water wolume few times an hour i think you are OK. Slow sump flow is good , in terms of letting you skimmer clean up the water better, i have maybe 90 g/h flow in my sump or less.
