Red and green algae on LR

[LouieB]

Hi my tank has been up for 3 months, 260w cf lights on 12hrs a day. I am starting to see this deep red algae and groups of green algae on my LR, should i leave it or remove it. I not sure but if i had to guess it looks like green hair algae and maybe cyano just need some advice? If its bad what can i do to get rid of it. Thanks.

The red looks like sponge, the green looks like hair algae. The sponge is harmless but the hair algae may become a nuicense. I'd manually remove what you can and test for phosphates.
