it will take some time, but if you have LR or LS in the tank allready, the smaller particles in the SD sand will become covered with the good bacteria and wont be so easy to stir up. I have 150 lbs of SED in my tank, added 20 lbs of LS from the lfs to seed it and it cleared up in 2 days.
If you can, add a few pounds of LS- it will help.
