After making a mix/soup for the next day where do I put it?

I am wanting to make a blend of mysis, brine, flakes, garlic guard, vitachem, and Zoe and then let it soak and prepare overnight before feeding my fish.

My question is do I put this soup in the freezer for fridge?

Also, with the flakes/pellets do I want to grind all this stuff together with the end of a syringe or do I just want to mix lightly?

 

I don't know about the fridge freezer question,but I would freeze it.

We blend - seafood medley, garlic, cyclopeeze, spinach and silver sides.
We put it in the food processor and mix it. Then with a spatula we put it in small ice cube trays, Freeze it and then bag it and keep it frozen. We make big batches that last a month or so.

Probably didn't answer your question but maybe it will help.

 

If it is meant for the next day only the fridge would be fine. If you are going to use it after the next day then freeze what you won't be using the next day.
