TDS value of our tap water
i just receive my TDS meter from Ebay last day's morning.so after i receive it,i quickly open the cap and test it on my tap water.
the reading for my tap water is 49-50ppm.i also try TDSing at my Aunt's house at Lembah Keramat and the main pipe at the road side.
the reading is also around 48-50ppm.
so my bet is that the whole KL has that kind of value maybe.
so my question is,is 49-50ppm safe to use for CPs?
