Most probably its diatom. You didn't mention your substrate or your tank age. If it a new tank and has sand as a substrate, most likely it is diatom. It will go away with time as the diatoms consume the silicate.
I am experiencing the same thing in my 10 gal right now
May be getting a couple otos would help? I hear otos eat diatoms. But then again getting a fish to solve algae (technically diatom isn't an algae) problem is never recommended. When it accumulates a lot in mine, I just spray H2O2 a little and it goes away for a bit and then comes back again.
Gist is, if it is diatom, it wont go away until they consume all the silicates. And it is harmless to your plants, only annoying and ugly looking.
