Re: [APD] chelated metals

[Wolf Scion <wolfscion at gmail_com>]

Stuart, thanks for the reply.

The AquaSafe says: "Substances in tap water that are dangerous to  
fish are removed or neutralized. Chlorine is eliminated and heavy  
metals such as copper, zinc and iron are neutralized."

Then, under ingredients among other things it says: "chelating  
compounds."

So, it sounds like you're right. AFAIK, most iron plant supplements  
are chelated anyway, so this product probably isn't "neutralizing"  
the iron in a way that makes it unusable by the plants.

Thanks,

Wolf
