How often will you be dosing the micro mix ?
May not need any additional Iron.
FE DTPA maybe in harder water if extra is needed and don't want to add more of the micro mix.

i can dose as often as needed. so far im doing micro 3x a week.
i want additional Fe because i dose this micromix lightly because of high copper amount in it.

how about EDDHA chelated Iron? is it any good?
it is more available and cheaper for me.
