What kind of filter do you have? The debris floating through the water will grind out a hang on the back filter, so you should be careful about that. The fish can survive the debris, but they won't like it. Do you have a tank to cure the sand in? If so cure it, adding a little sand to the aquarium at a time. Monitor ammonia and nitrates, get some prime that will help. If you want to get real crazy about it, use a turbidity curtain.
