Hello everyone!

First of all let me make it absolutely clear that I'm a no no when it comes to
chemistry my main subject is computer science but my hobby ask me to rub
shoulders with chemistry every now and then. I want to prepare a Trace Element
Mix for my 45G planted tank.. after going through an exhaustive search on the
net I found that I need to have Fe, B, Mn, Zn, Cu, EDTA for that, I manged to
get hold of the following

Ferrous Sulphate FeSO4 (For Fe)
Manganese Sulphate MnS04 (For Mn)
Zinc Chloride ZnCl2 (For Zn)
Copper Carbonate CuCO3 (For Cu) (not sure if I really need copper
since I think its toxic isn't it?)
Cobalt Sulphate CoSO4 (For Co)
Boracic Acid H3BO3 (For B)
EDTA

First of all am I on the right track here? I've got all the above in quite good
quantities (250gm each approx) now what I want to ask is how should I go about
mixing them (quantities) in a brew which is beneficial for my planted tank and
still safe for my fish I've got few gouramis and tiger barbs in there.

Any help in this regards will be greatly appreciated.
