My 6 year old Clown fish is sick...help!

[Carrera75]

My 6 year old black saddle clown fish came down with Brooklynella. I wonder if any of you know where I can get Aquarium Products Pro Formalin Fish Parasite Treatment locally. This medication is suppose to be very effective against this type of parasite. Any help or recommendation of any other medication or that works against this parasite is much appreciated.
