You should try to obtain the zooxanthellae from the lab that produce it. There is very strict protocol and transfer shipping regiment. Even with this they won't warranty that the culture stay alive. Anybody can put any dirty water in a bottle and try to sell it. Keeping living things alive is not always easy. Just cooling them probably won't keep Zooxanthellae alive.So this stuff isn't worth trying on a bleached anemone or coral?
Overview
Available for the first time ever: a multi-species, pure, live Zooxanthellae culture! PhycoPure(TM) Zooxanthellae is a blend of LIVE zooxanthellae assembled for use as an aid for marine reef aquarium corals and clams. Aquarists have reported great results ranging from coral recovery from stress events to enhanced overall coral and clam coloration.
Zooxanthellae are the symbiotic microalgae that live in the tissue of numerous corals and clams. They consume waste produced by their host, coral/clam, and in return produce carbon in the form of a sugar that feeds the host. It has been documented that there is an exchange of zooxanthellae between corals/clams and their environment.
All strains are aquacultured, pathogen free, and cleansed of excess nutrients. PhycoPure Zooxanthellae is cultured in purified natural Atlantic Ocean water and should be refrigerated. PhycoPure Zooxanthellae has no preservatives, is not subjected to harsh processing steps, and is batch processed to ensure quality.
Great results will happen when you routinely spot feed 2-3 times per week or broadcast feed 1-2 capfuls per 10 gallons. Whenever possible, it is best to spot feed corals and filter feeding inverts from a small syringe or baster.
