Red hair algae and red branch like algae

[NU-2reef]

Red turf is nasty stuff. My tuxedo urchin does eat it but the little guy jus can't get into crevices and sometimes carries some on it's back which sucks cuz Im pretty sure he helps it spread.

You're best bet is to remove manually. Try the boiling water in a syringe method and blast em. Do small amounts at a time and just keep at it till it's gone. But most importantly tackle the nitrate and phospahtes as best you can.

Another somewhat natural method would be to take a ball of chaeto and spread it out like a blanket over top of the nuisance algae and starve out the turf algae by making it compete with chaeto.

Last option is to take the infected rock and nuke it.

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.
