The shelf life of phyto depends on how you decide to store it. The following is the approximate shelf life:Originally Posted by sharkboy
Phytoplankton
Room Temperature
Alive, 1 day
Spoil in, 2 days
Refrigerated
Alive, 5 - 7 days
Spoil in, 14 - 21 days (yellow in color)
Frozen and Fresh
2 - 3 months
Brine Shrimp
Room Temperature
Alive, Shrimp will suffocate and die within several days if kept in a container. Brine Shrimp swim towards light so if you keep a light above them they will last significantly longer.
Refrigerated
Alive, 1 - 2 days
Spoil in, 7 days
Frozen and Fresh
2 - 3 months
A favorite for mine is to freeze the phyto and/or shrimp using ice cube containers. That way you don't have to thaw the entire batch every time you want to feed your reef and you significantly extend it's shelf life. But in doing this, of course, everything is dead and you have to be vigilant not to overfeed.
Thank you
