What are these tiny things?

I just looked, as I often do, with a flashlight into my tank at night. Swarming on top of the sand and swimming around are hundreds of pinhead size organism. I switched from CC to 4+" of sand and 1" of live sand. Could these have been in my live sand? or could they be new pepperming shrimp hatchlings? One of my shrimp was loaded with eggs recently.
