If your higher priority is to have crystal clear water than
you have to include very fine mechanical filters (cloth socks)

I disagree,.. Yes, for a time you will have particulate matter in the
water
collum, but after a tank has matured for a year or so, the particulat
mater
will be better filtered out naturally by filter feeders.

I guess we have different experience...
- I do not have mechanical filters in mine and my water is dusty.
Every time my fish feeds from the bottom sand there is cloud
of dust created which stays in the water column for a long time.
All crabs which sift the sand looking for food create small
fountains of dust going up to the water column... When the big
fish ****s to the water it gets spread all over the tank by pumps.

I do not know how many filter feeder animals you need to keep
in the tank to make the water clear of this kind of dust...
Maybe I need to see your tanks someday to learn how to do it.

Humm.....

Do you have a overflow box or similar? This should fix the particle that
maybe floating on surface or near it.
From Marc example -
http://www.melevsreef.com/sump.html
The combination of weir [overflowbox] and sump design, this should not be
any issue regarding particle on / near / at floating from the surface. Sump
should be holding those excess very very fine particle. In the tank, the
rest of the fine sand should stay put or settle quickly from the
disturbrance. The rest of the fine sand should be cover in slime or similar
to hold it down or atleast give some weight to it.

Tool should be use is OverFlow Box or similar. Any other filteration like
cloth sock ... etc not recommend it.
See pic 5 counting down from top. This fine particle should be flowing to
this area for the final resting place.

Marc, have fine example of taking care of this kind of issue without any
other mechanical filteration.
