    dpd powder has a black tinge???

    Hello all! Happy Spring!

    I opened my pool to sparkling water thanks to BBB.

    I was looking at my chemicals and noticed that my DPD powder (which is about 4/5th done) has gotten a black tinge to it. Has this gone bad?

    I've used the nastiest, crudiest looking powder you can imagine with no change in results.

    The FAS-DPD powder does get darker over time.That isn't a problem. But if it clumps up into a solid block you do need to crush it back into a lumpy powder.
