Hair Algae

[likwid]

Hey guys,

I have had my tank running for a year now, it is a 10 gallon nano, with 1 clown and 1 clown goby. Over the last few months I have noticed that hair algae is starting to cover my live rock. I have had an aquaclear 500 filter converted into a refugium with light and macro algae running for over a month, and since then the macro has doubled in size, but has not slown down the rate at which the hair algae, and algae on the glass grows. I am using RO water from a local store, and do a water change religiously every week. I even took out a small piece of live rock covered in hair algae out a couple weeks ago, pulled all of the hair algae out, and it is covered in it once again. My clean up crew consists of 2 blue leg hermits, 1 scarlett, 2 cerith, 3 astrea, and 6 black ones from Elite. My clean up crew does nothing for this algae. This is really frustrating. Any ideas?
