    Pfertz is nothing more than pre-mixed dry ferts solution. The only pre-mixed solution you might want to refrigerate is the trace mix, CSM+B for example. I never have done so, but I know some people do . You can add a tiny amount of muriatic acid to that mix, or a few drops of aquatic fungicide, and then there is zero reason to refrigerate it.

    As Vaughn suggest, no real reason.
    My guess is the brands that asked for it to be refrigerated have not added things like antibacterial but non active ingredients HCL etc.

    Seachem and Tropica have no such requirements, so that should tell you something right there.

    Why would they (pfertz) not do that as well?
    Seems rather odd to me.

    Cheapo CMS+B will get fungus, but a little HCL as mentioned, takes care of that.
    Perhaps that's what is being used and they did not want/think etc to add something like HCL to it for some reason?

    Who knows.

    I cannot get my significant other to allow Fish food/live food/aquarium stuff in the refrig. Unless I get refrig that only adds fish hobby items.........:eek:

    So that's out and I honestly do not like two different food sources in my refrig, cross contamination can occur/smells pretty darn strong.

    For my own macro/trace mix I use 2g/L Sodium Benzoate and 2g/L citric acid.
    Before that the mixture would be filled with bacteria or fungy.
