Your primary digging concerns will be some of the cichlids--which I know little about, so won't comment. Other digging fish, such as kuhli loaches and eels, will love the sand, but won't cause a problem.
Instead of rinsing and rinsing and rinsing, put the sand in dry, straight from the bag. Put a plate in the tank and pour the water onto the plate so that it overflows the plate and wets the sand without splashing. I did this on both of my tanks, with medium grain play sand, and haven't had any problems with clouding. Never rinsed any of it. I planted immediately after filling the tanks, and it didn't cloud then either. I don't know if I got dust free sand somehow, or if this really works, but it certainly has worked for me--this is how we put the sand in the SW system as well (and that was about 150 lbs of sand!)
