Fixing my sandstorm

[Shluffer]

I managed to fix my sandstorm by moving my powerhead and rocks. I'm left with an issue. The left side of the tank has a borderline DSP and the right side is bare bottom. I added a dusting of sand on the right and its staying in place, so I'm confident if I move the sand it will stay where it belongs. My question: How do I move sand without crashing the tank? Or do I just wait for the snails to SLOWLY spread out the sand?

I have enough sand leftover to fill the area, but I don't want to add it. Their is enough sand in the tank, its just not evenly distributed.

Thanks in advance
