TDS levels are ideally as low as possible after you have adequate calcium carbonate saturation, which we determine using the LSI. Since TDS includes calcium hardness and alkalinity, keep in mind that TDS below something like 500 ppm is unlikely. Most sources agree that ideal TDS would be somewhere between 500 and 2500 PPM in freshwater pools. 2

On more basic units the factor is automatically set to 0.50. A typical TDS factor for strong ionic solutions is 0.5, while for weak ionic solutions (e.g. fertilizers) is 0.7.

2020-04-06 · Total Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water, expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million (ppm). A TDS meter is based on the electrical conductivity (EC) of water. Similarly, is EC and PPM the same? Summary. ppm stands for parts per million & is the most common domestically used unit when measuring TDS. EC stands for electrical A TDS/ppm meter is a nonselective measurement and cannot differentiate among different ions. A more sophisticated piece of equipment is needed to perform those types of measurements. The value of 184 that was measured using a TDS meter in a prominent Huffington Post Article was not the lead concentration… it was the water's natural TDS level (which is dominated by minerals like calcium, magnesium, and sodium).
