If you get GOOD LIVE SAND,there should be NO CLOUD at all.When I switched over,the only cloud I had was from removing theCC. That is where the problem is.You WILL,No matter how carefull,Cloud the tank removing the old stuff.Best thing to do about this,is to pump out as much water as you can.Then remove the CC.You should also have some premixed water to make up for this lost water....Then refill the tank,,,Add the sand,,,replace the rock(oh,you aint got no rock).And you should be fine.....The Natures Live sand has enough bacteria in it so your tank won't recycle.As for the filter,,,Start it up right away.Just keep an eye on the filter elements.
