If your using live sand it shouldnt make too much of a mess. When I started my tank I was adding the live sand (forgot the brand, but the kind you can get anywhere including petco) slowly to the bottom cup fulls at a time then pouring out of the cup, then I realized that it was making no cloudiness what so ever... So i just ended up dumping it in, any cloudiness cleared up in minutes. That live sand shouldnt have too many small light particles in it, unless I just lucked out and got a good bag...
