Please help me id this algae! I’m frustrated

[Yates273]

Please, does anyone knows what type of algae this is? It has been going on for months. I keep up on my weekly water changes and pick it out each time. I have tried Flux Rx twice with no luck. Followed directions exactly as they say. It grows on my frags and is driving me nuts. Nitrates at 6 and phosphates are .02. I began carbon dosing 14 weeks ago since my nitrates were 75+. I’m thinking that’s where it started but now I can’t get rid of it. Fish won’t touch it. It grows on samdbed as well as rocks. If I remove a rock and spray with peroxide it goes away but eventually comes back. Plus I don’t want to keep spraying my rocks as they are not easy to pull out. I cut feeding to twice a day with my Plank feeder. I give algae strips every other day now. Any input I would really appreciate. Im frustrated at this point. Tank is about
7-8 months old

Looks like green hair algae. Snails probably eat it. It may not be easy to get rid. Keep up the eradication efforts.

I’m hoping it’s GHA rather than Lyngba but it really sucks. I just picked up a sea hare the other day, I’m hoping he helps me out. I just want this stuff gone. It has been a longer than expected battle.

Its green hair algae. Do you have a pic of the tank itself under white lighting ?

Here’s a short clip of part of the tank under white light when I added the sea hare. The worst of the algae is toward the back of the rockwork that can’t be seen.
But it’s all over the sandbed

I'd say Derbesia (a type of hair algae). under the microscope, Tell tale signs are branching of the strands, and the dark spore sacks (only during mature reproductive stage). Things don't want to eat it as much as standard hair algae.

Anyone have a successful way to treat Derbesia? So far my only positive is I saw my sea hare slurp some up but he doesn’t touch the sandbed and there are places on my rocks he won’t be able to get to.

I had a horrible experience with it. ticked off all my acros along with dinos and lost them all. Have been dosing recommended dose of vibrant for 4 weeks and it is 90% dead and gone. I would proceed with caution with your corals. It does have an algaecide in it from what I've read and heard.
