so when you are talking about "pores" you are basically just talking about keeping the WHOLE bed stirred, am i right?

Not really. Have you read Kip's sand bed article?
The sand bed critters travel in their tunnels and cause small amounts of water to travel back & forth. Stirring the sandbed actually closes these tunnels & disrupts the sand bed.
