I have hair algae in my CRS tank. I have a pretty big problem with it that came outta nowhere in the past few days. the tank is planted with plenty of java moss and a couple really long swords. I really don't want to scrap all the plants since it took forever for the moss to growout. the CRS are too delicate and expensive to add any fish to the tank, and they are sensitive to any chemical treatments (plus i don't like the algaecide products in ANY tanks). What can i do to get rid of this without killing my shrimp or starting over?
