I have a 29 gallon tank reef tank with a firefish, a yellow tang, and two clownfish ad some coral but my yellow tang has red streaks going down his side and middle of his body I just added a sump to my tank and a new light so I thought it was just stress and I don't have a quarantine so ive been treating it from inside my display and Ive been using melafix. how do I get rid of it. my ammonia and nitrites are 0 and my nitrates are high probably about 60 and all the others like the alk and ph are normal. I don't have a rodi filter so ive been using tap water with the tap water detoxifier and everything seemed fine for the past two months till now. my house has very hard water and that hasn't seemed to harm them. my nitrates just wnt seem to go down so im thinking about getting some nitrate reducer and im about to get a protein skimmer and a submarine uv sterilizer. please what can I do to save him.
