Hello, I'm not too familiar with iron as it is not something that we can exactly measure. However, I had one brown coral for about 4 months and was considering getting rid of it. After dosing iron, it turned into a very nice green coral. It's growth tips are blue so it makes for a really nice coral. Now most people that see it are wanting frags of that coral. I does 6 drops every Monday of that KZ iron. So, I can tell you it works. Hope this helps.
