    A friend tells me "mercury free bleach" is a must...

    Otherwise mercury will accumulate in the pool.

    Is there any credibility to this?

    It may have some credibility, however bleach is made through multiple industrial processes, and a quick google search showed that as of 7 years ago only 10% of bleach was still made with the mercury process (not sure if that was US or Worldwide though).

    The entire industry has been in the process of phasing out the mercury production process for a long time. Clorox has been completely mercury free for over a decade.

    According to this article in 2007, there were only 4 chlorine plants left that used mercury while 115 do not.
