Hello... I found this company earlier this year:

http://www.hawaiianmarine.com/

They used to be listed as a reseller on the Dupla site but I can't find them
on there anymore.

I have not order from them (yet) so I can't tell you if they are good.

Hello All,
I have searched far and wide for Duplarit K (in the US) and cant find
anyone who sells it. Do you have any suggestions where i could buy
this or any substitutes? I have used Dupla before with spectacular
results. The tank had so many plants that i started trading them for
fish at the local aquarium store

Thanks
nitin
