Are these diatoms?

[Jeremy Lain]

Are these diatoms or is this the beginning of algae? Can someone confirm this?

Do you have a picture that isnt under the blues? Hard to see what is really happening :(

Looks like it is probably diatoms. If it is, within few days to a week you should see more, including on the sandbed. The tank looks fairly new and it's almost a guarantee that diatoms will show up in new tanks at some point.

This is what it looks like under white lights.

Update on what the tank cycling is looking like and the diatoms. Does this look like the diatoms are going good?
