I have thought of fridge but the conclusion I com up to was no need of it
If I only fill the bottle I dose from with enough for 5 - 7 days and it will be stirred every hour and prior to dosing. what´s the worst that will be happen? My answer to myself - when my thinking was miles away from the box - was - Bacteria break down the Chaeto cells, hence release more protein, amino acid, sugar, other compounds and surplus bacteria, hence feed my filtrating animals. However - the rest of the Jamama juice I did - is in the fridge until I put it in my dosing bottle.
If you dose with zooplankton you want to have them alive during the time they are in the dose bottle. I think that´s more a question of food than temperature. Sooner or later I will try to combine zooplankton with phytoplankton and see if this can be automatically dosed.
