Dupla, the company, was bought out by Red Sea. Hawaiin Marine was a
Dupla distributor. When Dupla became part of Red Sea, Red Sea dropped
Hawaiin Marine. Dupla products will be available again eventually from
Red Sea distributors.

is a valid email address and they will
send you a catalog if you ask for one...

the only Dupla products they carry are the Plant products and Dupla K
is one of them... I just got my catalog this week from them, just send
them your mailing address in the email and request a catalog!

www.redseafish.com does NOT list the dupla products though but it is
an active site in all other aspects.
