If iron is known to eventually break free from its chelator (even if you use the most potent chelator DTPA), then isn't it a bad idea to pre-mix a month's supply of Plantex CSM-B micros with distilled water? Towards the 4th week, your CSM-B micros solution will have very little usable iron.

Is this correct or incorrect?

Which iron chelator is used in Plantex CSM-B micros? Gluconate? EDTA? DTPA?

Hi,

No particular problem, partly the condition in the (hopefully) darkened bottle are likely to be a little different than your aquarium. If you are concerned a shot of white distilled vinegar or a shot of hydrochloric acid. Mainly if mold is a problem.

I have not checked recently but as of a couple of years ago it was EDTA in Plantex CSM.

Respectfully,
Joe

The Fe chelator in CSM+B is EDTA.

No, it will not break free from it's chelator because most of the other metals are chelated with EDTA.

That is an excellent answer!
