Burgundy algae

[Anthrilliel]

I have a 3 month old 20 gallon tank. Lights run for 9 hr white and 3 only blue.
Temp 78.5
Phos 0.07
Ammonia 0
Nitrires 0
Nitrates 15
Salinity 1.024

The past week or so I notices this hair like algae and the last 2 days or so I saw the burgundy/dark red one as well. The red one does not brush off . Is this some sort of Coraline?

What can I do to control this?

It looks like cyanobacteria but that would brush off easily. If it's hard then I would say red coralline. Very nice!

You also have bryopsis, those fern like growths on the rock. You will have to treat your tank with flux one day, they will explode and choke out your corals.

Flux as in fluconazole?

Correct!
