We started our tank last week for the first time with new sand and rock. Once we added the water it was cloudy, but cleared up some after 24 hrs, but its still looks cloudy. Also everytime we barely touch the sand it makes the entire tank cloudy and tanks 24 hrs to clear up enough to see the rock. Is this typical of new sand and how long might this last. Its kinda hard to do aquascaping when you cant see anything and when you can, one touch of the sand clouds up the tank again. Any tips or advice?
