Diluting Dupla drops in DI water...OK?

I've been looking at various auto-dosing schemes for Fe baring
fertilizers... like the Dupla product.  Does anybody see a problem in
diluting these drops into de-ionized or RO water?  Say a weeks worth into a
gallon or two?  The idea would be to have a small powerhead pump kick in
perioidically to deliver a dose.

Yes, yes, it's not hard to add drops every day!  But the idea behind a new
tank in the works is automation.  (But no robotic fish, please!)
