TDS is made up of inorganic salts, and a small amount of organic matter. Usually inorganic salts include calcium, magnesium, potassium, sodium as a cation (positive charged ions), and carbonates, nitrates, bicarbonates, chlorides, sulfates as an anion (negative charged ions). Those solids can pass through a filter with pores of around 2 microns (0.002 cm) in size. Therefore TDS is a measure of the amount of material dissolved in water.
The variations in TDS concentrations have enormous impacted on the aquatic life as it changes the density of the water that will limit the aquatic life growth or may cause death. Furthermore, on the aquatic plants, since higher solids (TDS, TSS) decrease the passage of light through water leading to less clarity,
