It's fine. It's only diluted, no conversions. The "unbinding" can be 
done by time, heat, bright light, and chemicals rxns.

I don't use Seachem kits, but I would venture to say yes. And, yes, 
ionic iron is usable. Fe +2 is ionic, as well as most constituents 
that make up our marco and micro solutions.
