Are these dinos or diatoms?

[finnaest1]

I recently got a tank and have had it for almost a month now. I used precycled rocks and media from the previous owner, and all my tests have shown good parameters. Recently though algae has started to pop up all over the place. I tried to scape it all off yesterday but it is already almost fully back. The bulk of the algae have clear bubbles on the base and tips of them and are brown. I am wondering if these are diatoms or Dino’s. I got a uv light just in case, but want to ask everyone’s opinions. thank you

Looks like you got a little bit of everything in there. First year is a struggle when using dry rock. Try introducing some live rock or established media or sand to speed up the process
