to stir up the sand you could try a sand sifting gobie but I would wait abit , also sea urchins are good for eating rock clean when you go through your algae cycle. Are you using rodi water?
You may run into lots of algae problems later on if you're not also another fish to look into getting once the tank has fully cycled is a golden rabbit fish. I swear by them their great for keeping rock clean.
