If you are planning exclusively for iron dosing suggest you can give ferrous gluconate a try I have been using it for ages in my tanks - so 10g for 500g of water to make the solution, and dosing 1 ml/100L of water. but if you are going this route - make sure it does not come in contact with light during any time of the day(the stock solution)
Good judgement comes from experience, and experience comes from bad judgement.
Few of my works
