    as you might have realized... I have at the moment an interest in traces ;)

    Lately, I feel more and more annoyed by color of the water. It is clear, but has a brown/yellow color. I know the culprit: 90 ml traces per week. I could of course use active carbon or add less traces. But I won't. (like high traces)

    I now wondered whether the colour is solely caused by iron. Zn, Mo, B are white and Mn and Cu are pink and blue, respectively.

    So is there something I could do?
    Are there fertilizers around without Fe? And which Fe chelate is the least brown? fe gluconate?

    greets,

    yme

    Lighting might help somewhat also, switching from less yellow bulbs to red/blue mixes might help.
    Fe Gluc is green.
    DTPA is a nice reddish yellow.
    ETDA yellow etc.
