Red hair algae and red branch like algae

[Coralgurl]

Some pictures...there seems like 4 different types here - green, red, wiry, and branch. Also, in the last photo, theres something with green tipped tentacles. I've been watching this for a while, seems there are about 4 heads, they retract when touched, but not into rock, just into a polyp.

Based on NU-2reef, best option is to blast with boiling water? There's another active thread on this method so I will read up on it.

I forgot to mention, I have 2 54w T5H0 fixture, I changed the white bulb last month, was told the blue was fine for another few months. (supplement lighting with LEDs)

Thank you for the help.
