Brown growth on White rock

[MorrisMustang]

My tank has been set up for about a month and a half. Over the past few days I noticed this brown growth starting to develop. Not sure what it is.

Is it time to add inverts? Or is this something I need to treat chemically?

Likely diatoms mate. All part of the cycle. Let it just take its course.

Anything to be concerned about? Am I to do anything differently?

Nope it happens to all tanks. It’s part of the cycle process. Just keep monitoring your parameters and you will be fine.
