I think I have hair algae, its brown and sort of looks like fluffy stuff. Its on my plants and on the inside of my tank on the glass. Accompanying it is light mild brown patches on the glass too. Is it hair algae? What about the brown patches? Is that part of hair algae? How can I get rid of this? Is it safe to use algae eating fish if my tank hasn't cycled yet? What about treatment?[/i]
