Calculations to get the right concentration of Fe using flourish?

Flourish shows that Flourish is 0.32% iron. So, if you want 1 ppm, or 1 mg/liter of iron in the tank, add 1/.0032 mg of Flourish per liter of water, or about 300 mg (.3 grams) of Flourish per liter, which is 300 ml of Flourish per liter of water. Would somebody check this to see if I made a decimal mistake?

 

Vaughn, I think you did make a decimal mistake somewhere. From my calculations its approx 0.3 ml of Flourish per liter of water to achieve 1 ppm of Fe.

 

Yes, I did make a decimal error. .3 gm of Flourish is only .3 ml, not 300 ml.

 

Here's a pretty good calculator for commercial ferts:

I haven´t seem any discussion on "DIY" micros as we do for the macros. Why is that? The chemicals for trace mixes are not available for the public as KNO3, KH2PO4 etc?

Thanks,
