I am 4 weeks into trying clear choice.
So far so good.
I had no problem with the chlorine method I just know chlorine is not good for living things and with clear choice I can still use a little chlorine if the water gets "off"
It was a little foamy and gross the week of flush.
Now all has been great.
It is used every day.
The water is clear and does not smell like chlorine or sour water.
Sanitized is not a good thing most of the time. It is not healthy to be sanitized.
No bacteria = no life
Bottom line 4 weeks and it has been better for me than traditional methods.
