In what way could they be problematic how would a filter sock become useless

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?
