How long has your tank been setup? Sounds like Diatoms to me, common in new tanks.
You can leave the molt in the tank if you want to your clean up crew should make short work of it.

if you are topping off your tank with tap water you could easily get diatom outbreaks. if you are it is highly suggested to top off with RO or RO/DI H20
