if you take a close look at the picture here it shows 2 sea urchins that my friend used to clean his tank. The urchins are almost directly in the middle and front of the picture and if you'll notice the rocks just to the right of them is white. he had put them in to fight algae in his tank and to my amazement they really cleaned house, i mean tank! the rocks became white like the first day he had put them in.
