New Tank 45 days woke up today with some of this on rocks ‍♂️

[Lololo]

Anyone know if this is normal and eventually will go away or is it even bad at all? I started my Biocube 32g 45 days ago recently removed the protein skimmer and just left the intank media with filter floss bio ceramic ring Chemi Pure and last de nitrate also have the refugium with Chaeto still trying figure out what to put now In chamber one since protein skimmer was removed maybe I’ll get better one later on tanks still fairly new don’t think I need atm. If anyone can identify this green stuff thanks

I have a biocube and has been set up just a little longer than yours. I have the exact same algae growing on mine. I'm assuming it's harmless. Just seems like your typical green algae. From what i've read and heard. It will go away and is just part of a new tank.
