Frag Rack Issue

[Ace6090]

I have what I think is Dino's but only on my frag rack. I don't see them anywhere else in the tank. Does anyone else have this issue?

All parameters are stable.

Might be cyano. I would blow it with a turkey baster.

I blow it off every couple of days and it keeps coming back. You can see it's on the frag plugs too.
