Val, I have super hard water too but fix it by running it through a Brita Water Filter which brings it down to a 6-6.5 simply by running tap water into the pitcher. I see you are in a different country so you may have to mail-order for one but maybe you have them in stock already or another brand of water filter that has the same workings inside. I haven't gotten inside of the replaceable filters yet but they appear to be filled with tiny charcoal-type nodules. I really don't know how it works but just know it does...some kind of ju-ju maybe, but seriously, it really does work!
