We need some more information before we start making suggestions.

What size is the tank?
What type of lighting are you using and how much of it?
Any form of CO2?
What kind of fish/plants are you keeping?


Fill us in and we will be able to help a lot more.

and what else you are dosing. NO3, PO4, general trace elements, etc.

the fact that your plants appear to be needing Iron means that you may need to start dosing all traces a little more, rather than Iron specifically.

If you need Fe you will probably also need Mg (epsom salt). But before anyone just tells you to start dumping stuff in a tank we need to know what you have in the tank currently. Water tests, No3, Po4, is there CO2... etc lighting and more info the better.

what correlation is there between Fe and Mg? They should be independent of eachother. Fe is a trace element, and Mg and part of GH.

I was thinking the same thing... What does iron have to do with Magnesium? If your trying to increase your GH, then you shouldnt be adding Mg alone. You need to use calcium and magnesium in equal poroportion.

Mg aids in the plants ability to use Fe, thats why deficiencies in Mg resemble deficiencies in Fe.
