Concentrate iron

I have a 30 ml very accurate dropper bottles and I want to dose my iron daily. Why? Because I like the daily interaction. I know 20 drops is roughly 1ml or so they say. I tried the fertilizer calculator but I am still not sure how many grams I need to mix with the 30 ml of water. I have 8 gallons of water in my tank and I want to about .5 ppm or a little less of Iron for my plants. Can anyone help me?

I would approach this from the other direction.

1) How much dry fertilizer do you want to give the tank in one week? (what formula/kind of iron is it? Are there instructions with it? Can you look up instructions?)
2) How much liquid do you want to dose at any one time?

If you will be dosing every day, 6 days a week (and one day off for water change) and you can dose 8ml each time, then multiply 6 x 8 = 48 ml.

So, put the amount of iron you need for 1 week in a bottle.
Add 48 ml of water.
Shake well.

Dose daily @ 1ml per gallon.

I understand your approach but I only have 30 ml to work with and that is where I run into my poor math skills.

Mix 4.5 grams of 10% Fe-DTPA to make 30 ml solution.

1 ml = 0.5 PPM Fe for your 8 gal (30 liter) tank.
