These may not be diatoms anymore...

Are these diatoms still or could they be something different, or are diatoms dying and reforming? I'm confused. I'm at about.the 1 month, 1 week mark since putting biospira and first fish in. Some of this algae is Dark brown, some very light brown. Some rust colored (a yellowish rust) like diatoms I'm assuming. And a few spots of very dark brown.

It’s really hard to know for sure but likely diatoms. Either way, you will see lots of cycles for a while (think months, not days) so I would try not to worry. Good luck.
