I have Red Lace, Red Gracilaria, Chaeto, and Ulva Macro Algae in my 24 gallon for aquascaping and it's in my refugium in my 95 gallon. If you want pretty plants, you'll have to stay away from tangs because they'll eat it all up. I usually pull some out of my fuge to give my tangs treats in my main tank. i only have a dottyback and clown my 24 gallon, so the macro algae doesn't get eaten.

Also, I've been green hair algae free for 6 months. It was very drastic, but I took out all of my live rock and scrubbed the green hair algae off and drained my sand before transfering it to my new tank. I do 25 gallon water changes every other week and have cut down my feedings. I also started adding Magnesium, Strontium, Iodide, and other trace elements to keep my Macro algae healthy and growing. They are absorbing all of the excess nutrients before the green hair could get to eat.

Good luck

Can you recommend a site that sells any of these micro algae?
