Must be bryopsis

[Pvtgloss]

Been battling this for a free months. Cuc won't touch it. I bought a lawnmower blenny who won't touch it, even if I pull it and make it small. Bought a sea hare that won't touch it. FluxRX is on the way.

Hair algae, not bryopsis IMO

I wonder why the sea hare won't touch it? He's the right species.

Battled it for over a year in my tank. Did reef flux and a week later it’s spotless

Did it look like what I have? Did you have to shut off your uv channel on your lights? I'm just trying to figure out a have plan.

I have a way of removing the hair algae that works well. I take a wooden dowel about 12 inches and zip tie a round tube cleaning brush then I can bring the brush into the algae and spin it around like making cotton candy.

I'm doing that tonight! Do you siphon whole doing it or does everything stick to the brush?

It did and no. The only thing I did was was remove carbon and turn off skimmer for the first 24 hours.

That works great, I have a similar setup. My issue was that I have a very large tank.

Use a longer dowe.

Definitely not bryopsis looks like hair algae to me also. Here's a picture of my lettuce nudie sitting on bryopsis. Bryopsis looks more like ferns just FYI. I would reach in and manually remove as much as possible and just continue to do that. I'm not a big fan of chemicals.

Not hair algae nor bryopsis but derbesia which is similar to bryopsis and is labor intense removal.
This is one of the more challenging of algae due to need of its complete removal. Removal is best accomplished by taking the rock out of tank and placing in a container of tank water. Then you will want to pull as much as you can by hand and discard. With a dental pick or small crochet needle, pull the roots off the rock. YOU MUST GET EVERY ROOT OR IT WILL SIMPLY RETURN !!
After you are done return rock to tank and reduce white light intensity and even hours of white light and add the following cleaners which will help with control. These guys will consume bryopsis but not as fast as bryopsis can grow - They will never keep up.
Pin cushion urchin, Chiton snails, pitho crabs, and larger astrea snails

This procedure is not as bad or time consuming as it seems. Assure phosphate levels do not become elevated which helps feed this algae
