it will take a few days to clear up, especially if you didnt put something over the sand when you poured in the water so as not to stir it up(like a plastic bag)
If your filter is on you can also toss some cheesecloth on top of your sponges to collect the fine loose material in the water. It should be clear within 72 hours or so.
