DT Phytoplankton

[stevil]

I accidentally left my container of DT Phytoplankton out overnight after feeding my fish... I have normally kept it in my refrigerator.

 

Is it dead? Still safe to use?

You can smell the difference when it goes bad. It'll go bad even if you keep it in the fridge. Does it smell like sulfur?

All I can say is I unfortunately did the same thing, more than once! When I put it into the tank, the fish ran like HE$#!

So, in my opinion, it's garbage time!
