6. Total dissolved solids - Wikipedia

   en.wikipedia.org/wiki/Total_dissolved_solids

   Hard water can cause scale buildup in pipes, valves, and filters, reducing performance and adding to system maintenance costs. These effects can be seen in aquariums, spas, swimming pools, and reverse osmosis water treatment systems. Typically, total dissolved solids are tested frequently in these applications, and filtration membranes are ...
