Re: More fun with plumbing...

Toni, that example you posted is my setup.

The numerous holes were not so much a filtering system as much as a protection
for my reeflings, so nothing go sucked against it and died.  Anemones or
cucumbers would be a good example, because they can crawl right over it, and
with the many holes in the screen, the water is sucked in from the other side
and the creature has the ability to crawl away to its new destination.

You don't need a sock or sponge to filter it that much.  But you also don't want
sand running through the innards, because it will affect the SCWD in a bad way,
as was shown on ReefCentral.com

For hoseclamps, if they are out of the water, you can use SS clamps. If you need
to use some in the water or near the surface, you should get some like these:
