Hey All,

I cant seem to find a trace mix where I am from so I decided to make my own.
My tank is 100 gallons while my water is 8.1PH which falls to 7.1PH after CO2 injection.
I was able to obtain DTPA FE 11%. The rest of my mix is comprised of Manganese Sulfate Monohydrate, Zinc Sulfate Monohydrate, Copper Sulfate Pentahydrate, Boric Acid, Sodium Molybdate Dihydrate.

The following table represents my percentage analysis:
Chemical Salt NameElement of Interest Percentage Content in Chemical SaltAmount of Chemical SaltsAmount of Element of InterestPercentage of Element of Interest in TracemixTrace Element Amount in
EI Method
Dosing ½ Teaspoon or 3g
DTPA FE11%290.30g31.75g8.82%0.26g
Total of Trace mix359.93g

Is my dosing a half teaspoon okay (3g)? Or should I use a little less than a teaspoon? Like 2.7g?
Please advise, did I use sufficient amounts of the elements in the trace mix?
