Hard water at Doltala, Madhyamgram


I stay at a housing at Doltala, Madhyamgram. There are white deposits on utensils, bottles and the washroom walls and floor and on the taps.Despite regular cleaning the deposits are difficult to remove and develop into scaly deposit with time. The filter that I use, too has deposits. I am not too knowledgeable about the pH or any other content of the water. I need to know the solution for this if any. Its becoming difficult day by day.

Kindly help
