I purchase my freeze dried Cyclop-Eeze from Jayson at Saltwater Connection. I believe Jayson also carries the frozen now. My Selcon is ordered from Dan at MOPS in Ontario.

Although the Cyclop-Eeze is an excellent coral food, {perhaps one of the best}, it is a bit more expensive. However you would not require an extra supplement with it.

I used the Selcon or something like Boyd,s Vita-Chem, as a supplement with brine shrimp or flakes or even with mysis, {which are more nutritious}, as Bob mentioned.

Selcon is actually more of a supplement for fish than corals. More expensive also. I used it and the Boyd product in my mixture, because it was also fed to the smaller fish and such. They are also pretty expensive to supplement coral food with.
