New stuff appearing on sand

[AdamR0331]

Is this dark stuff appearing on my sand algea of just bacteria or something that shows its the beginning of a cycle? Tank is 30 days up and running as of today and I have been running my lights cause I have 4 corals

Hard to see in blue light.. can you take a white light picture? I’d guess diatoms with a tank of that age thou.

Diatoms

I’ve got a new tank (2 months) looks just like my diatom bloom, be patient it should clear up itself (once silica in new sand/rock is consumed I believe)

Diatoms.. it’s harmless and will go away… it’s a byproduct of a cycle basically
