Hi All! Is this good or bad algae? The red started first and now we are seeing the green as well. I did a few 5g water changes as the Nitrates were 15-20. The hairy stuff is being taken care of by the blue legged crabs. It showed up after using seed. The rock was pretty clean until adding the seed besides the red/purple stuff. Tank has been up and running since the end of November. There are 2 clowns, 1 flame angel, and 5 blue legged crabs. Nothing has been added since late Jan.

Looks like you have a few different types going, including hair algae and possibly dinos.
