Got live rock for my dry rock last Friday - now seeing this. Normal?

I am currently cycling my first reef tank. I got about 10 lbs of live rock to mix with my 20ish lbs of dry rock.. today I saw this brownish beige particles on the rock and sand. What is this stuff? Should I be worried?

No normal part of cycling , there diatoms and feed on silicate they should go away once the tank becomes established.

Indication of cycling is near its end

Diatoms- meaning cycling is near an end point and first algae starting, beginning of ugly phase. Clean up crew for diatoms can be added at this point.
