Reef Discussion
Hi Susan, hard to tell much from that pic (I'm sure fish make it hard to get a pic) but from what I can see, that looks like a physical injury to me. As Slin said it will probably come good if your tank is stable and the fish not stressed.
I don't keep tangs so somebody with better knowledge of these fish may correct me but as long as its active and eating, I would just keep an eye on it for now.

What you got to remember is there are high quality GAC products out there that are not aggressive in the way they extract toxins from the water. Some are look like pellets , some look like powders , some made from bamboo others made from coconut and so on.
I use Korallenzucht brand as it's non aggressive , if I used a more powerful type I could expect RTN or STN on my acros.
I would find it very unlikely that a brand such as zeovit would cause problems since it is recommended in the basic filtration method and used in conjunction with the rest of the basic filtration products.
For now...... I believe your tang has a bruise that's going to go away , not caused by previous water quality issues.
I honestly don't think it has hole in the head either that would be unlucky.
Futhermore here is the zeovit basic guide for some light reading.

It probably just got startled and went bang into your live rock. As the others have said, it will heal. Just keep an eye out for secondary infections etc.
On the other hand, my female clown has a lump under it's chin. When the clown is really stressed out the lump can get reddish and it takes a long time for it to go away.
I hope your yellow tang doesn't have something like this.
An aside, it occurred to me the other day when I was looking through an aquarium book that had close up photos of corals and fish in a natural reef environment, just how many little deformities and abnormalities etc that natural reef inhabitants have. For example there were some sps that had patches of dead bits here and there. Just made me feel more grateful for the fact that most of my fish are near perfect. Well actually, on closer inspection they aren't. In fact they are far from perfect! My female clown has a recurring lump on it's chin and my bloody coral beauty hasn't had a tail for about three years (imagine explaining that to visitors).
My yellow tang is rare perfection.

When a wound is red on a fish, it signals inflammation. I do worry when I see this as it can be a sign that infection is setting in.
Best remedy for it though at that stage is a good water change and a high quality diet which you are already doing.
