hi all

i want to dose iron to my tank and i have found that most of us uses the Fe Gluconate ( 12.46% ) , but i have only a source for ( Iron (II) D-gluconate dihydrate. 98% )

My tank is 150 L and i am using the EI method so according to this Yet Another Nutrient Calculator i should be dosing 601 mg Fe Gluconate (12.46%)

so how much if i want to use the ( Iron (II) D-gluconate dihydrate. 98% )
