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

what should the flow be through the following?

Refugium
UV filter
Charcoal filter
Phosphate filter
Water polisher
etc etc etc.

all are very low requirements, other than the possibility that the skimmer MAY work at 10 times turn over why would you do it?

The filter sock would loose efficiency because it requires high flow to capture as much particulate as possible. You keep restating your point, your logic is understandable but I need some concrete proof (And no I'm not going to call Euro reef and ask them) before I believe it.

The reason I don't believe you is because I own a skimmer, I have 7X turn over in my main tank and still get a very large amount of skimmate production.

If I slowed the flow down even more to the sump would I get more concentrated skimate...? I highly doubt it, again nutrients don't only exist on the surface they are mostly found dissolved in the water column. Considering that letting your skimmer have more access to the polluted water makes more sense.
