Can bromine, potassium and iodine be mixed?

[TheDragonsReef]

I have a free slot in my dos and already dose bromine, iodine and potassium seperately. I was wondering if i could dilute them all in rodi water and dose it from the same container or will they react with each other or participate out?

And if they cant be mixed together could i mix them into my alkalinity, calcium and magnesium containers?

What exact chemical forms of these are we talking about?

Assuming reasonable forms, my only concern is the iodide slowly oxidizing to iodate when diluted. Iodate is less bioavailable.
