Is it possible to buy the chemicals separately and DIY the micromix?

I would order if I had access to it from my country, but that is not the case, so I end up having to buy expensive branded mixes.

Thanks,
Evandro.

Sure, if you want to buy 2000lbs, they will make you what ever, as long as you are buying large enough amounts, otherwise, yuo can make it yourself with various salts and then chelate yourself, I'd rather not do that nor do the analysis to make sure I have a % trace metal in the chelated product.

say if i get my hand on some Gluconate Fe, could it be possible that i could mix my own drops? whats the ratio of Gluconate Fe(g) to water(ml) and how many mls per 10 gallon?, thanks Tom.

Depends on the purity of the Fe to Gluconate.
If you assuem 100%, then Fe to Gluc will give you the mass for Fe.

So if the ratio is say 1 milligram of Fe for each 2 grams of Gluc and you add 3 milligrams to 1 liter to get 1ppm of Fe.

Sorry, I am not Tom, but maybe can help...

Go for the drugstore and ask this drugs - TOT'HEMA, Fergon®, Ferralet®, Simron®. The brand sold locally depends on country.
It is impossible that your local Drugstore have no such drugs (cure for anemia etc).
I am using TOTHEMA $5 (20apm.х10ml, Fe=5g/l), French brand long time ago TOTHEMA.
It is all almost pure ferrous gluconate or Iron(II) di-D-gluconate.
There are Cu and Mn but amount is negligible for planted aquarium.
They are cheap and lasts for a long time for a 90cm tank. Use as an additive to your regular micromix if it's not work (hard water-high pH).
Good 911 in case of Fe deficiency, as ADA ECA or Seachem Flourish Iron.
You can also use Dissolvine® D-Fe-11 (11.5%) from Valagro, Italy. It is a strong Fe-DTPA chelate stable up to pH=7.5 and GH=20 for 80%.
BREXIL® Fe is another option. It uses relatively new organic chelate LPCA (ligninpolycarboxylic acid) stable up to pH=12. (I never used it)

Well the aquariumfertilizer website seems to be down. Just checking in for an update Tom, any progress? Is the site just down temporarily? Do they have the micromatrix mix yet?

Hi Tom!
Its almost a year since you posted this but still I can't see the new mixes on AquariumFertilizer. Any problems? Any chance to see them soon? What you offer in these ferts is very exciting!
