My drinking water is classed as soft with low levels of Ca and Mg. Most of Scotland's drinking water supply is soft as the raw water (before treatment) is surface water which has not percolated through the ground. This is in stark contrast to the south east of England where most of the water is hard as it is groundwater from deep aquifers. There is no public health issue as far as I know in the UK with regards to the difference in mineral quantities and no need for supplements in Scotland. I bought a new coffee machine two weeks ago and the manufacturer attempts to get you to subscribe to regular deliveries of filtration units and descaling products which I don't need and won't be ordering. The machine came with some test paper to test the water and I think it measures the concentration of CaCo3 in the water. My paper changed colour slightly, although whether it was due to it just being wet or registering a chemical reaction I cannot be sure. I did look up the latest sample readings from my supply (Rosebery A) and they were 8.68 mgCa/ l, 1.61 mgMg/ l and 29.05 mg/ l CaCo3. It would be interesting to know the difference in the mineral concentrations between your raw water and RO treated water, Udhay. Perhaps using test papers if you can get a hold of some. Although I am not a tea drinker, I do believe that more reddish colour tea is seen by some as the *true* colour that one should strive for. The darker, more muddy colour is due to the higher levels of Ca and Mg in the water. I know that Yorkshire Tea do a blend specifically for hard water.
