    I bought some Pura PhosLock GFO about 2 months ago, I ran it for less than a week in a bag. When I removed the bag I just put it in an open container and it dried out....can I re-use it?

    Just wanted to check before throwing it out, this stuff is not cheap.

    If, during your first use, it was not "expended" then you should be able to continue using it.

    The key, when you reach the point where PO4 is not reduced with the application of GFO, then it is time to replace the GFO...it is expended or consumed...

    There are those experimenting with regenerating GFO but its not an easy process and probably not worth the effort. Just drying it out is not sufficient as it has adsorbed the contaminants in its structure.
    Depending on how long you used it and what your phosphate and silicate (ferric oxide filters out silicates and arsenic too)levels were to begin with it may or may not still be good.
