Here is a quote from Dr Ron
"most desirable of substances, "mud." Generally, what a sediment-studying scientist would refer to as fine or very fine sands with smidgen of silt, most normal folks call mud. These are sediments whose particles generally range from about 1/16th mm (0.063mm) to about 1/8th mm (0.125 mm)."
his recomendation is that 40% of your sand bed should be of this size range, by washing your sand you will most likely be getting rid of a lot of this size.
for what it is worth I dumped all my sand into the tank of water strait from the bag.. it took a week or two to settle out but now I can fluf it with my hand and it settles out right away.
kgb to answer your question, if you have critters and rock in the tank it will settle out fast.. it just takes a few days for the smaller particles to get covered with bacteria and become heavy enuf to fall out of solution.
