Have yet to use; storing with a partially used pouch.
This is a very educational living project that my family and friends are amazed with when I show them and still to this day amazing to me. I have been feeding them with out any problems and enjoy watching the light up and reading about how and why they do it and the benefit they have on our air on earth, I was amazed how important they are to our survival.

Excellent nutrition that I do not have to mix! perfect!!
The plankton seem to love it, they are doing well.
As usual, quick response with a great product. My 4+ years environments are doing great with regular feedings from Pyrofarms!
