I bought some DT reef formula phytoplankton and accidentally put it in the freezer over night before noticing the "DO NOT FREEZE" label on it. Is it garbage now or can I still use it?
It's no longer phytoplankton. Closer to Marine Snow. Freezing it kills the algae and bursts most of the cells. It's probably somewhat useful but nowhere near as useful as when it was live phytoplankton.
