I wasn't aware GLA sold premixed iron. If you are asking to how to mix the dry fertilizer it depends on which dosing method you are using.

Iron supplement is dry in bag. Looking for amount of dry fert to mix with water in the 500ml. bottle.
What is usual PPM most people try to achieve in the planted tank.
I am using the PPS-Pro method

PPS method targets iron at 0.1ppm. The dry iron comes in several varieties. It appears GLA only sells DTPA 11% iron.

You can calculate how much to add using this calculator. The amount to add to your 500ml container also depends on the volume of water you will be dosing and the dose size you want to use.

If you need help using the calculator feel free to ask.

Thanks a bunch. 17.206 grams in 500ml to get .01PPM.
See if that's correct.

Depends on the dose and tank size. What size tank do you have? What dose size are you going to use i.e. 5ml, 10ml etc.

That'd be 0.1ppm, not .01. Assuming 4ml.
