I have had my tank for about 3 months now and my sand is starting to turn a redish brown. I have a cleanup crew of snails and hermits. I also have a pencil urchin. My snails to a fairly good job on the glass but the sand is getting filthy. Anybody have any suggestions as to what I need to get or do for the sand. Also alot of my snails go to the top of the aquarium and stay there instead of cleaning. Anybody else have this problem or know why they might be doing this??? Please Help!
