one more question about the sand

[billyjoe]

The tank is clear but there is some sand on the sides of the tank in the indside, will that settle also, and will snails help with that problem.

it will settle eventually...I hope you don't mean you have already put snails or anything else in the tank yet though

Is this a fully cycled tank in which you changed out the substrate to create a DSB? The sand will eventually settle. If it sticks to the front glass you may want to wipe that off with a paper towel. If it settles on rocks or corals, use a turkey baster to blow it carefully off. If the tank had already been cycled, it is safe to return snails and other creatures to the cloudy water. If it is still the extreme "milk vat" cloudiness you could hold off another day or so. It sounded like you were already past that stage.
