I use both in my tank.
Cyclopeeze is one single zooplankton food that works well for larger lps corals
Coral Frenzy is a mixture of phytoplankton and zooplankton of varying sizes that will feed a variety of corals in your tank.
My mixture I do is Coral Frenzy, Cyclopeeze, Oyster Eggs mixed in water and zoecon for a half hour then I turn off my pumps and pour or target feed the mixture.
