Tank and sump turnover rate

[MitchM]

I'm on the lower end of the scale, 2X turnover.
I don't understand why people are talking about dwell time in a skimmer and sump turnover rate. They're 2 different things aren't they?

Turnover rate is what your sump return pump is running at and dwell time has to do with the height and water throughput of your protein skimmer. Correct me if I'm wrong.

I prefer as low of a sump turnover rate as possible, while maintaining healthy water parameters in the display tank. I actively feed my corals and don't like the idea of having the food filtered out soon after I add it.
I keep on top of the tank parameters by measuring phosphorus and nitrate levels, weekly for now.

Dwell time in sump near skimmer, vs dwell time of contact in skimmer. Not sure it matters, dwell vs turnover in the big scheme of things, but lower sump turnover is silent for me, so I go with it

Yes, dead silent for me too. Close to the bed so major consideration.

To me a skimmer is just another type of filter that gets it's feed from the sump.
I also use a 10 micron sock for Fozdown and a 200 micron sock from the display tank overflow.
That's it.

Yah I have a recirc skimmer so Im not worried about my skimmer at all. At this point my dt is maintaining the same temperature as my sump so I feel I have enough flow. I would just like a little more to help with clarity a little which is just more flow through my filter socks. Either way Im gonna leave it for now and if the tank runs well with no problem algae or nitrates I'm not gonna worry about it. I do have so great pod and macro growth in my fuge. Not sure if thats due to low flow though.
