Black hair algae taking over my refugium


New member
About two weeks ago I cleaned my refugium and now I have this black hair algae (greyish black), just noticed it last night or the night before. I didn't have it before I cleaned it ( did it in the back yard so must have picked up something there). I don't see it in my display tank yet (sure there are spored OMG). Should I take down the refuigum and clean it again? Is there any treatment or is the best thing to redo from zero and clean it really good? Guess the live rock that is in there is toast. It is growing fast, has doubled over night and is choking out the Chaeto algae.
