Alright guys, I;m trying to help one of my friends out that I work with that is now as well informed on some of the saltwater tank topics as the rest of us are. So, the problem he is having right now is with hair algae like crazy. I'll post a picture but it is in clumps and I'm pretty sure it is hair algae. I tried to explain to him that he needs to not overfeed, change the water some, i just recently helped him order a good CUC from reefcleaners.org(excellent order by the way John!) but now he thinks that some sort of fish is the answer to the problem at the moment. I told him to try some boiling hot water and spray it on the hair algae in different cycles to kill it in the mean time & I also explained that a Phos-ban reactor is the best way to go to provide results over a long time span but he does not have the funds for that at the moment and does not think he is ready for the setup of a phos-ban reactor yet so he was looking for advice on a type of fish to get that would eat hair algae? I was thinking maybe a brown scopa tang? Are there any other tangs or surgeonfish that may work or maybe a algae eating blenny? The algae is so thick in the picture though that I'm not sure any fish will approach it. But I thought I would humor him as I promised to do some research & come back with some answers for him, so what do you guys think?
