I think it's possible that it's Cyano that is sitting on top of the dinos on the sand bed.
This is where the first sign of dinos is that reefers notice.
I thought I had diatoms shortly after I restarted the tank almost two years ago, but after months the brown patches on the sand persisted and they have never left.
A good way to find out if you have dinos is to turn off all pumps and blast all the rocks with a single powerhead and wait for 5 five minutes.
If it's like fine dust coming off the rocks and they form strings in the water column when free swimming it's a good indicator of dinos.
