Is this Detritus or something else?

Tank is about 2 months old, 3 fish (2 clowns 1 royal gramma). Just started feeding them mysis shrimp. These started out small but now after about 2 days its everywhere. I work nights and plan on doing a water change tomorrow and siphon the sand. Yesterday I used a turkey baster and stirred everything in the sand up but it settled and now looks worse and now its also all over the rock. Maybe I'm over feeding? A few days ago the sand/rock was immaculate.

Diatoms, natural part of a cycling tank. Let it be it will clear itself

Yep just Diatoms will go away. Looks like you might be getting bubble algae in that first pic up on the rock. It wont hurt but some think its unsightly and it does spread quick. If you decide to remove it make sure you don't pop the bubbles or the spores will spread. Just remove and scrub the rock in some tank water.
