Thank you for my greensand filter, ordered from you Sept 2010.

It has made a huge difference in the quality of my water, and I am very pleased.  Beforehand, the water always smelled like sulfur, terribly so when sitting in the pipes for any length of time.  After installing the filter, the smell disappeared and has been gone ever since.

I have been adding Potassium Permanganate at 3 to 4 month interval.  The Fleck valve is set to 1200 gal between recharges.  I love this feature and wouldn’t have it any other way.
