What's on my glass?

[flightjunkie]

Can anyone please tell me what are the green\yellow spots on my glass? I'm also seeing some of my LR getting similar coverage. Is this Cyano or Diatoms?

By thew way, this yellow\green stuff as come on at the same I've had a copepod explosion.

Video comes into better focus around 15 seconds.

Any information would be helpful.

Thanks

Probably diatoms algae.

Total score for you. Look at all those Copepods. With a splosion like that it means there's a lot of food. Looks like an algae to me. Lotta food bieng eaten lotta poop higher bio load. One probaly started the other.
Is it crunchy or slump or come off easy.

Thanks guys.

Saltyfilmfolks - it feels crunchy when I try to clean it off. Any idea what that means?

IMO either a corraline or another calcareous algae.
