Mixing Dry Iron Chelate

I ran out of Seachem Iron, and decided to go with dry Iron, simply ofr costs. I asked around for a good formula, iron/DI water, the target being Fe range 0.1-0.5ppm. Here's what I got, in case anyone is seeking the same info:

7g in 1000ml water - dose 5ml/10gal for .1ppm
14g in 1000ml water - dose 5ml/10gal for .2ppm
21.5g in 1000ml water - dose 5ml/10gal for .3ppm
27.5g in 1000ml water - dose 5ml/10gal for .4ppm
34.5g in 1000ml water - dose 5ml/10gal for .5ppm

It depends on what dry formula you have as well. EDTA 10-13% fe, ferrous gluconate, ect all contain different % of iron. Which are you using?

I thought GLA had the mixing ratio somewhere on their website? I'd have to find it again.
