I have a Nature 2 sanitizer installed after the filter for my inground
pool. Been using it for the last 6 or more years.
I use fewer tabs per season now than before I had it. The cartridge is
advertised as being good for 6 months, but since I am in the NE US, our
Summers are barely 3 months, so I use it for 2 seasons before replacing..

I had one of those once, but I never saw a difference in chlorine use.

Does that mean if you kept the chlorine at lower levels than normal
you wound up with noticeable water problems? Not that I disagree
with you, just curious. I'm skeptical about the science behind
it. The sales info is also misleading, as it
implies that normal chlorine levels cause eye and skin irritation and
odors. In fact, burning eyes and chlorine odor come from chloramines
which are combined chlorine that comes from a pool that needs to
be shocked.
