Seems a tad dark for cyano...so probably a type of algae. Whats with all the hair algae around it?

Nope not the dreaded red cyanobacteria slime looks just like a regular red algae it's really pretty stuff. easy to maintain it reminds me a lot of kelp you feel its slippery and rubbery like kelp. Most tangs like to eat it. Fishman

I don't think it is a macro algae to me it could be a type of cyano or maybe a turf algae ReefCleaners.org | Clean Up Crews and Macro Algae - Nuisance Algae ID Guide You really need to figure out why you have so much algae, how old is your tank and are you using ro water.

Tank is 4 months. I use rodi water. Run a skimmer and filter. I've also checked my phosphates an nitrates and they are fine. Don't know why I have hair algae

The hair algae is probably using up the nitrates and phosphates. I have noticed that tanks go through stages as they become established usually marked my different algae growths. Doing smaller more frequent water changes usually helps my algae problems, That red algae looks like Red Turf Algae, or Red Wiry Algae. I have a problem with that in one of my tanks because it managed to come in on a frag, it was so small it didn't see it before I put it in my tank

If the red turf algae isn't harmful I don't mind it. Doesn't look bad. I just hope it doesn't spread
