I wouldn't, anytime you're adding more chemicals to your water you're asking for trouble. Let it sit for a few days and let the gravel settle. If there is that much stuff in your tank that it makes the water cloudy with debris, consider vacuuming more often. If it's more a "milky" cloudy, that is just a bacteria bloom (a good thing) that shouldn't be disturbed and will go away on its own within a couple days.
