EI dosing using this "local" trace mix/chelated iron

This is the analysis data of the trace mix (as written in the box) in %W/W
-----------
sulphur as sulphates: 6.29
calcium as carbonate: 10.00
magnesium as sulphate: 3.62
manganese as sulphate: 2.88
iron as chelate: 2.73
copper as sulphate: 1.25
zinc as sulphate: 1.00
boron as borate: 0.09
molybdenum as molybdate: 0.0038
---------
I am assuming the chelator for the trace mix is EDTA because the box and origin is very similar to chelated iron below.

The chelated iron is listed as Iron as complex of EDTA: 13 %W/W.

I want to dose using dry salts if possible

Thank you very much for the help

The copper content for that mix looks high, but I'm not sure about that. You could reduce the percent of copper by dosing only half as much, but adding iron chelate to get the total up to what you want the iron to be.

Yea that copper is going to be high if you want shrimp or anything else copper intolerant as nearly all the food for them have trace copper already.
