Read Plantex CSM has EDTA and mixing with DTPA makes for wider range or chelates hence more iron absorption if recall correctly.
Came across a picture of the stability of different chelates at different PH:
Picture from this sight
Perhaps answered part of first question. That still gets me curious how hardness comes into play when chelates break down.
My other question, is the H in HEDTA toxic to fish or is the OH fine?
Would be great since this stuff is cheap at a local nursery.
