Gosh Layton you do seem to be getting rather muddled. It is the result of the experiment you have offered to do, which was to set up a small tank and dose with whatever you think is leaching from zeovit, to see the effect.
But first you will have to figure out what it is you think is leaching from zeovit, no point asking me, I'm just as confused about what you think it is, as you are.
You have claimed it is some form of iron, but as you are the one making the claim, you are the one who will have to decide what form of iron you think it is, I really don't know why you asked me for, I wouldn't have a clue.
But myself and others do have a genuine interest in your experiment and are keen to see you go ahead with it.
