Possible Dino outbreak need help id’ing

[gearish]

So u came home to find my tank covered in brown maybe slightly greenish stuff at first I thought it might be diatoms but I just want to be safe, I did use a turkey batter to blow it off the rock and sand and looked like it disappeared or lessened. I’m also confused because I added a new skimmer so the micro bubbles are freaking me out cause I don’t know if it’s from the skimmer or Dino’s. Parameters are as follows
Ammonia 0
Nitrite 0
Nitrate 5-10
Phosphate 0-.02

This is a new tank so it could be diatoms or potentially dinos starting out. Majority of the time it is just diatoms. The bubbles don't look like dino so you should be fine. You should bump you phosphate up a bit and add clean up crew(sand conch, trochus, astrea) since your tank seems cycled. Everything that's going on is normal.
