Hair algae on the brain

[Ruth]

I hate to tell you this but I think your tank is still cycling and I'm afraid that brain probably does not have much of a chance. One month is really early to try to introduce corals into a tank. When I set up mine I waited a good 5 months before I put anything other than live rock, sand and fish in there and even the fish did not go in for 2 months. Who knows though maybe you will be lucky and have it survive. My experience with brains is that you do not have to target feed them as they get most of their needs met through the water column and light. I would wait before adding anything else until both you ammonia and nitrite are reading 0 and your nitrate is below 10. Good luck.
