Shelf life of kits? I am approaching the second year with the kit I bought from Ben. I would assume that the chemicals do go bad (Especially the dpd powder). Should I dump the whole kit and look at Trouble Free or Leslies? Thanks!

If you've kept the reagents in a cool, dry area, then you can use them for several seasons. If your dpd powder isn't black and in clumps, it's usually still good, too. I have a bottle of the calcium reagents that is from my original PS233 kit, and they are still measuring accurately, when compared with new reagents.
