| Good to hear from you Sue. I have changed out 3,500 gallons now since 2/21/08 when the softener went into service. I love it, no more adding de-chlorinate. The GH is 107.4, KH is 161.1ppm and PH is very stable, morning 8.4 afternoon 8.6 and ORP has been up steady over 240 to a high 298. Water very clear, my 6.5 year old three step kohaku hi is still light along the scale edges, not sure if this is age or what. I still plan on dropping to about 74ppm or a little lower, will see what happens. I believe the biological increase with longer sunshine and warm temps will cause the KH to drop faster and lower compared to winter and fall. My KH lows last winter were 125ppm and last fall 107.4 fall with weekly water changes-interesting (seams a good way to judge balance changes in bio and filter production, based on how these values run. It is great learning water quality of your own pond.
