Sand

[Z_almero]

just replaced me gravel with some white sand but, cant seem to get it clear enough, its always so merky, as apposed to when i had my gravel in, how can i clean my water if the sand specs are gonna get all over the place?

It'll probably take a week or maybe even two for the sand to settle down all the way. What will happen is the sand will get a "biofilm" on it which is a film of bacteria and that will keep it down. I'd give it some time and I think it'll be OK. I have sand in a FW 55 and don't have any trouble with it...I even vacum it gently when I service the tank.

As long as you cleaned the sand before you put it in, then it's just a matter of letting the smaller particulate settle into position and realize it has a specific gravity greater than that of water (I won't get into micro-air and all of that). As Loganj said, it can take 7-14 days.
