Water kinda cloudy after day 2, will it settle or go away soon...

Patience. I setup a 10 from a 5, and it was pretty cloudy. Set it up Sunday afternoon--by Monday morning, it was crystal clear. I'm a big fan of using lots of current to get the particles to drop out more quickly. Maybe add a powerhead for a while? Don't aim it at the substrate, or you'll stir up what's settled, but have it really move the upper levels of the water.

Removed, or bound in with organics and bacteria. I don't do much vacuuming on the substrate of planted tanks, because you want that stuff left in place for the plants.
