AFAIK, conditioners don't 'neutralise' metals. That implies they've somehow
disappeared or became useless. These bottles chelate them.

That is - makes them harmless to aquatic animals and plants.
Plants and animals can still make use of them.

Your plant supplements are also chelated metals.

Others will correct me if I'm wrong ;-)
