I suggest you read the whole article also--there IS mention of adding chemicals. My yellow tang's red streaks disappeared without the water changes OR chemicals. However, mine was not scratching itself on the rocks....that sounds more like ich to me (what is the amonia level?), and perhaps in your case the red blotchy streaks are a result of abrasion rather than a bacterial infection?
