Red algae overgrowth

[Epicanimal]

My tank has been growing a lot of red thick algae on rocks and sometimes over corals like my Zoas and micromussa.

how could I get rid of this?

Cyanobacteria

lower phosphate... no light for a few days... suck it out.. if you cant get rid of it.. use chemical.

Yes it is cyano. Nothing to worry about. Siphon it out. Over and over again with each weekly water change. Get more livestock (corals) to use up your nutrients and block the light the cyano is getting. Reduce your lighting. All these things will help. I assume you have .1ppm - Phosphate and 5ppm to 10ppm nitrates.

It still grows over corals. So do I just clean that off as well

Looks like Dino’s to me. Can you take some close ups . Long stringy , snotty and has bubbles?

Does it roll up like a mat at night?

What’s your water params?
