    My water hardness was off the chart, followed instriction, worked great. It also helped to balance pH and KH.

    Althought initial charge of this pillow lats 48 hours (recharge needed with API salt, purchased seperatly), but my desired level was achived within 2 hours, therefore PLEASE CHECK EVERY HOUR, otherwise water will become too soft.
