hold the hose an inch above the sand to suck up dirt, a little sand comes too, but nothing noticable.it looks dirty quicker, but i like that, lets me know when i need to clean it. with gravel it falls though and piles up.can cause a stir with faffing about with the tank when adding plants and decor, but nothing too bad. once settled, it usally fine with everything
