    I just need some math for this one. If I have a liquid hydroponic trace solution that I want to use up that has a Fe concentration of .2% how do I determine how much to add to get a concentration of .4ppm iron in a 250L tank.

    Thanks

    100% is well, 100% of the solution, so 1,000,000 ppm, or 1 kg /liter.

    What is 0.2% of of 1,000,000?

    2000ppm or 2000mg/l

    250 liters is 250,000 mls.

    I think you should be able to work the rest.

    It's well known how bad I am at this sort of thing (bad, really bad), but you will need 50ml hydroponic trace solution to add .4ppm Fe to a water column that size.
    =.4/2*250
    = 50
