Algea Identification please

[SaltEpidemic]

New tank, couple weeks in, rock was cycled months in brute trash can, one piece however was pulled from another system.

Need some help identifying what I got growing in here, and how to address it early before it turns into a real problem, thank you in advance!!

White stuff is sponge, have it all over my (once) dry rock, not much you can do, harmless and will usually go away on its own, brown stuff is diatoms, same thing as sponge, not much you can do, beneficial part of the cycle though. Bright green stuff is cyanno, spreads quickly, dosent hurt anything but is an eyesore. Could do a tank blackout or manually remove them, though the best thing to do IMO is add copepods, IME they will eat that stuff

I just looked today and noticed pods crawling on my glass, so they're in the system for sure

Should take care of it, bottomed out nutrients are another cause, same with a long light schedule

Update;

Tank is infested with pods, coraline showing up, brown stuff gone.

So does anyone know of anything I can add to the tank that would eat this white sponge? It has spread quite a bit.... thanks in advance.
