Anyone had any luck getting rid of hair algae?

You could try hydrogen peroxide. Read this

I know you said no to vodka dosing but when I had HA problems, that was the only think that got rid of it. And it disappeared really fast. I think within a week of vodka+MB7 dosing my HA had mostly melted away. Now I do 0.6 ml vodka daily and the tank is sparkling clean. Don't go the biopellets route. The more I see people having issues with them, the more I'm convinced they can do more harm than good. Vodka dosing gives you better control over the process.

Between that and a seahare you'll have the issue nicked in no time.

Peroxide does work but I really need to stress that peroxide and living tissue is a seriously bad combo. I've read some horror stories of this trick going badly for some people. I work with peroxide and work and know first hand the damage it can do, especially in the presence of UV. If you run metal halides, only dose the peroxide after the halides go out otherwise you are making radical species which go all Chuck Norris on anything alive it comes in contact with.

#1 tooth brush plus elbow grease. Do little every night.

Snails wont touch the long hair algae but they will keep it in check after the rock is scrubbed.

Gfo won't hurt and some say elevated Mg will help also.

sounds like an nutrient spike causing the algae bloom. I had something similar when I reset my tank this past fall. All sorts of funky algaes, cyano, etc popping up where it never used to before. Then I decided to put my BioPellet reactor back on line to more aggressively attack nitrates even though it was already pretty low at <4ppm (certainly not Ultra Low, but I've never had algae problems with that kind of a nitrate reading in the past). Anyway, a few weeks of that and the algae started to die back. I also had to change GFO more frequently (like once a week!) because it was getting used up pretty quick. Probably due to phosphates leaching out of my old rocks. I' think I've sucked it all up now cuz I'm back to once a month replacement with the GFO.
