Hi all. Since is my first post here I'd like to introduce myself:
I'm Andrei from Romania, and I'm 36. I'm a computer programmer and my aquarium is my primary hobby. I'm browsing this forum for a long time, but only now I found a question which have no answer here already, so now I really need you help, guys.
I'm very determined to make my own micro fertilizer hopping that it will be better and cheapper than the brand ones.
I'm still learning the knowhow from various sources and, of course, even at the step 0 I ran into problems.
It's not very hard to make the recipe itself, al least on the paper, with a little knowledge of math and chemistry but I'm stucked at the actual preparation of the iron chelates. I intend to use EDTA, DTPA and HEDTA as chelators and FeSO4 as iron salt because it is easier then FeCl3 to manipulate.
So... does anyone know what are the specifics of the chelation reaction in case of DTPA and HEDTA? (for the EDTA chelation I managed to find all the parameters).
I mean, is the proportion the same as in case of EDTA, 1:1 molar Fe:chelator?
What are the temperature and the pH recomended in the chelation reaction when using DTPA and HEDTA? Do I stir or not? ...And so on...
If anyone can give me any kind of information about this I'll be very grateful.
Tom, I understand you cannot (and for good reasons) give your own recipe of you micro fertilizer, but can you give me/us some clues? I must say that I not intend to sell the fertilizer, I only want make it for me and my friends. And I swear I will tell everyone that you helped me alot. (Anyway you helped me already since I read this forum from cover to cover)
Thanks,
Andrei.
