Hello i have 15g nano reef started about month ago. There 2 Ocellaris clown, and some corals(you will see them on pictures). The think im worried about is brown algae, in the beginning all rocks were brown but now i notice there are some little hairs(dont know this is the right word, you will see on the pics). I think this is because my high level of NO3 - 25ppm, which i cant lower with water changes. I have protein skimmer too. What about dosing red sea NO3O4-X or some other method to get rid from this algae? Thank you!
