New tank, possibly diatoms

Picture isn’t very good.
I got a light dusting the day after a water change.
It’s a red-brown color.

Fixes?? Like I said I just did a water change. And I’m running carbon reactor. Tank is a nuvo 10

Tank has been up for about 2 weeks

A shot under white light would help a lot. Looks like the whole tank is pink.
