Chalice Power is a concentrated blend of several varieties of dried zooplankton developed by Justin Credabel to be the ideal food for raising and maintaining chalice corals, such as Mycedium, Pectinia, Echinopora, Oxypora, and Echinophyllia. Chalice Power is formulated with a range of particle sizes, and the particles are heavy, so they sink rapidly in the water column. This feature makes Chalice Power easy to feed directly over the coral, mimicking the natural suspension-feeding behavior of Chalice corals. Also an excellent food for all filter feeding invertebrates, such as other soft and stony corals, anemones, feather duster worms, clams, sponges, and tunicates.
