Hair Algae in Nano Reef

[Miquel]

Have been checking past threads looking for suggestions on a herbivore that I could put in my nano to clen up some hair algae. My lawnmower blenny wont touch the stuff sadly. As its only a 20 gallon tank I cant find any fish such as tangs that will be comfortable in such a small tank. Am hesitant to try crabs unless Im positive theyll eat the stuff. Am working on reducing the nitrates to starve it out but would love to have something that would help things along

Try a Phosphate buffer in a media bag. Have you checked your phosphate level?
