Prolly diatoms, this is common in new tanks, or in tanks that go through a new cycle. This will gradually dissappear as the nutrients are cycled into other food chains as they develop and the system matures. As an alternative, when doing your water change this week, siphon out the "dusting" and discard the old seawater. This will remove the nutrients that drive the bloom with the biomass of the nuisance organism. The usual excess nutrient with diatom blooms is organic silicate, which the diatoms make into the 2-part tests for their outer coat. Once the system matures and you have some age to your live rock, sponges will uptake this silicate to build the structure of their colonies. The use of RO/DI will eliminate a potential source of organic silicates in your top-off water.
Hope this helps.
