Do the Dosing Containers require an air-stone to maintain a homogenous dosing solution?

I was wondering, do you need to add some kind of movement to the liquid in dosing containers? Like an air-stone? I was just thinking after time maybe things separate and so could be dosing concentrated amounts.

No but I do stir 2x per week as bottom tends to be chalky looking
