Red algae with cheato

[Rmckoy]

After my old grow light blew . I had a spare grow light so installed it .
it doesn’t flow pink like the old but cheato is still green and growing .

What’s the red algae ?

I believe cyano. Best way to keep it off is to rotate the algae. Also na circulation pump to aggravate the surface. Reduces nutrient build up the cyano would eat.
