I want to re-aquascape my planted tank. To do that, I'm going to have to move around my fluorite and sand, and that's just gonna make it really muddy. Could this have any negative effect on my fish? I never rinse anything, I just kinda pour it in there, so I know it's gonna get real cloudy. My friend said she lost a lot of fish that way, and I just want to make sure I'm not gonna kill anybody.
