Our planned new home out in the country will have a septic system, probably a non-aerobic type. I recently read that a water softener using potassium exchange resins is easier on the septic system than the sodium exchange resin type. Could someone explain exactly how these things work, why one would be "easier" on the septic than the other, benefits/downsides to the piping, cost/maintenance comparison between the two, etc....or should we just go without a water softener. We live in central Texas and the water is pretty hard. We get white water spots and the faucet aeriators (sp?) tend to clog with lime buildup.
Thanks for any advice
