i've been cycling a tank for nearly two weeks now, and the ammonia and nitrite levels are down and everything seems fine. i've been doing daily water changes through the process. a coupld of days ago, i lightly vacuumed the gravel out of curiosity to see how much gunk was in there so far and also to make sure food wasn't collecting (i.e. was i overfeeding? don't think so). ever since then the tank has been very slightly cloudy. not so cloudy that you look at it and think, "gee--that's a cloudy tank." but just enough that you kind of want to rub your eyes and think, "is that water cloudy or is it my eyes?" i know, however, that it's the water, because it used to be crystal clear, and nothing else that i look at looks cloudy! 
i'm wondering what has caused this, and why isn't it going away? also, i want to avoid using chemicals to clear it up unless someone tells me for sure 100% that it's okay to use something.
