Brown stuff on LR

[DottyClown]

Hi, can someone help tell if this is diatom or somethng else?

It started appearing again, just 1 day after I scrubbed the LR clean of them.

Would really appreciate some advise and help on this. Thank you.

Bro, it was soft and powdery so i just siphon it out during weekly water change. Now I hardly see it anymore. Still no idea what it was.
