Hi dinnese,
I like to make up my iron smaller amounts, so I follow the recommendations of Rex Grigg. Rex sells 10% chelated iron and these are his mixing and dosing instructions:
Chelated Iron
* Mix 35 grams of powder with 2 cups (473 ml of water).
* 1 ml of this solution will raise the iron level in 10 gallons of
water by 0.2 ppm.
* Suggested range for iron is 0.1-0.5 ppm
Since the iron you have is 13%, approximately 27 grams of the iron should give you an equivalent solution and dosing level of 1 ml per 10 gallons.
Hope this helps!
