    Is this a reasonable substitution? If so, how would the two compare by
    weight? (The formulary is out of KI, whereas I have plenty of KBr.)

    Well, as I read further, Anchel states that the properties of the
    iodide as opposed to bromide have never been fully investigated. So
    I'll have to locate a source for the iodide. It turns out that
    aquarium supply stores carry several brands for coral & crustacian
