Diatom bloom after moving the tank

I moved my 24 gallon tank from upstairs to downstairs a week+ ago—with nearly all the water removed, rocks pulled out, and with the sand substrate getting sloshed around pretty well. I believe there's now a substantial diatom bloom. Brown powdery stuff covering the sand and glass. Easy to remove, feels gritty and not stringy. I don't think it's dino's or cyano but I haven't looked under a scope.
Should I take steps (like reduced feeding/lighting etc.) or just wait it out. I'm assuming the major disturbance to the substrate and rocks triggered the release of nutrients into the water (i.e. silicates).

It looks like after moving my 24 gallon tank from upstairs to downstair where I had to remove nearly all the water and rocks—with the sand substrate getting sloshed around pretty well—that I now have a substantial diatom bloom a week or two after the move. Brown powdery stuff covering the sand and glass. Easy to remove, feels gritty and not stringy. I don't think it's dino's or cyano but I haven't looked under a scope.

I just moved a 10g into a 20g. Same argo sand bed, same rocks, same water + 10g about 2 weeks ago. Had an ammonia spike and new cycle again. It's progressing quickly, but I think you are right about stirring up the system.
