Green hair algae

[Electric eel]

Mr Wilsons advise was very good. There where some issue that i had not addressed. All the advise has been great. I have tried the sea hair once and i am now on my number two try. The sea hare does not seem to climb the live rock. It seem to want to remain in one area of the tank and so far is not looking so good. I have purchased a Scoupa tang to see if it will eat some of it. So far not so good either! I have and will follow some of the advise given. BUT my main question is "How do I get it off my rock" Will it go away on its own? Should I remove all the rock and do something to it? I will not keep the tang or the seahare if they do the job. I will pass them on.
Any advise on the hair on the rock would be great! Once again Canreef members ROCK! I also purchased Rowphos to put in my sump. I also have carbon in there also. both are near the exit. Should they be placed in a certian order? Rowphos first then carbon or???

Thanks everyone
James
