    Default Water Softeners - Potassium vs sodium chloride salt.

    Does anyone know anything about using potassium chloride salt instead of sodium chloride salt in water softeners? Will potassium ions affect the orchids similar to the way sodium ions do?

    Water Quality Answers
    Can potassium chloride regenerant wastes from a water softener be used for irrigating lawns?

    It is true that living plants take up and utilize potassium, whereas plants cannot use sodium. However, there is far more potassium in softener KCl brines than plants or grasses can normally use. Potassium that is not taken up by plants is held in the soil by clay and organic matter. Excessive build up of either potassium or sodium in the root zone of plants can inhibit plant growth.

    It is possible however to collect the KCl regenerate wastes from a water softener in a third tank, dilute it with non-softened water and apply it to well established lawns. The Water Quality Association recommends, in such cases, a minimum dilution of 75 parts of non-treated water with each one part of regenerant waste water. We also advise that grass clippings be removed at each mowing, and that the lawn be irrigated with non-treated water at least once between each application of diluted softener regenerate waste water.

    Ornamental plants and fruits and vegetables are often more sensitive to dissolved salts than turf grass, so a dilution of at least 200:1 is advisable if KCl regenerant waste water is used in areas where these types of plants are growing.

    The regeneration "brine" goes out into a dry well or some place. The potassium and sodium ions I'm concerned about are in the softened water. Sodium I know is bad over 10 - 25 ppm depending on genus/species, but what about the affect of the potassium ion in the softened water on plant growth ... specifically orchids?

    The only thing i can suggest is to wash out the pots with clean non softened water once a month.when the guys installed it did they give you a hard water source also or are all the outside faucets soft water also?the brine goes into the septic or sewer,the drain!I think if you didnt leach out the pots the salts will build up and cause root damage.You might want to buy a reverse osmosis filter system for the plants its a bit expensive at first but its great for the plants,to drink,and to clean things with belive it or not.I will ask the rep that we get our softeners from and let you know about the potassium

    I have a whole house water filter that uses potassium pellets instead of sodium. We installed it to battle the high amounts of chlorine that was driving us crazy (smelled strong, turned us red, tasted bad, etc.).

    I water most of my 40 or so orchids with this water, and have for years. I do flush the pots often and I water my mounted plants with distilled water. I don't seem to be having trouble, new growth and blooming plants here.

    For whatever that's worth. I'm sure this isn't ideal, but I've been making due.
