Five to eight years ago, EPA made the treatment industry get rid of the good stuff treatment and try a new treatment....it doesn't work.  I have had to replace a few boards of decking about seven years old that was stained and sealed.  Not only does it rot quickly, it also splits much worse than the older ACQ treatment.  Manufacturers changed to another new stuff (I think it's MCG) about five years ago, so we'll see in a few years how well it holds up.  At least it doesn't split as bad, so far.  I've got all three treatments and I can really tell the difference.

Advice: wait till winter to replace or build with treated lumber.  If the lumber is put down in the sunny, hot season, it splits and warps immediately.
