Is iron needed in a reef tank? While it can be a limiting factor, I think it precipitates so fast it isn't in any measurable level even in NSW. And as above, it contributes to algae growth. There is also some question about the addition of chelants (usually EDTA) to your reef tank.
You've got to be tough, if you're gonna be stupid!
