Aluminum and iron?

As I noted in your other thread:

I do not see any reason for coral deaths based on those values, and I'd look for other reasons. Can you describe the tank in more detail?

You might benefit from a trace element supplement, but if the tank is getting fish foods and some normal water changes, it is likeyl getting enough trace elements to not cause deaths.
