Help with algae identification :)

[Erik the Red]

Hi guys,

can anyone please help me to determine whether those are nuisance algae or not?

The tank is 2 weeks into live rock cycling: NO3 2.5ppm, PO4 unknown (forgot to buy the test kit!)

lights are working as the tank was already cycled, because i want to make sure everything is fine when i will insert the first coral...

thank you! Have a nice weekend


all the round-shaped algae have flat leaves


those dark red algae grow slowly, so i bet its some kind of macro algae

Bryopsys!
I shut off all the lights and trying to shade the tank.

should I increase magnesium as well?

i am wondering when i will finally be able to populate the tank :mad:
