I guess you're trying to make PMDD. I had a real problem getting chelated trace, but a fish shop in another part of the island sells their own. Quality stuff to, high pH stable chelating compound. I've no idea where they get it from, and it is sold in bottles with hand written labels, not a "make" as such.
This is, of course useless to you, but what I'm suggesting, is maybe ask at the best lfs's in your area - you may strike gold, well, Boron, Copper, Molybdenum....
You could also look at TheKribs list here, if you are over there.
Just so you know, fishfood contains every trace plants need. Although that does not make fertilizer useless, in many low fish stocking high plant stocking setups the fish are not enough to meet the plant's needs.
www.gregwatson.com sells a chelated (Fe+) PMDD mix, but I think they're out of stock over there at the moment. Any rate, that's where I'm going to get macros, very reasonable price. As for trace, I'm using Flourish, which has Fe.
