I only put on a sock if I have stirred up the sand or blasted my rocks and kicked up a detritus storm.  I don't normally run mechanical filtration otherwise.  I really don't like washing filter socks and ya, throwing out filter floss on a regular basis is definitely not in my cards either.  This is  a great question because this is another one of those personal preference kind of things.
