Dirty decorations?

[ZoeNC1]

Hi everyone! So my 29 gal tank is almost done cycling (Yay!) but I’ve started seeing brownish spots on some of the silk plants I have. Does anyone know what’s going on? Also how to get rid of it. I don’t know what it is and would love any ideas.
Thanks

Its Diatoms. They show up in new tanks. Just scrub them off. They go away eventually.

Probably brown diatoms. It's common in newly cycled tanks, they'll eat up whatever is feeding them (I think it's silica?) and go away once it's gone.

Oh ok thanks that’s good to know

Its probably harmless, but ugly, Diatom algae. Very common in new set ups. Eventually green algae overtakes it.
Petsmart sells long handled aquarium maintenence brushes. Works like a charm knocking algae off decor.

That sounds right I did a bit of research and it matches what I’ve got almost exactly. I’ll look into that brush the tank is rather tall so a long brush would be handy.
