What iron chelator is in TNC Trace Mix?

You might have to try to contact the company for that info.
Fwiw, their Complete Aquarium Plant Food lists EDTA.
Their Iron AT lists DPTA which is good for pH in the low 7s but by the time pH gets to 8 about 80% of the iron will be precipitated out.
The strongest chelator is EDHAA which keeps iron available up to pH 9 or more.
They don’t list a trace mix on their site so perhaps they no longer offer it.

They don't do it any more, It was bought more than ten years ago if i remember, it's when you could get all the different salts from them.

Mostly for the worse.
