What is TDS? What is it used for?

 

Our chemistry expert explains in video all you need to know to treat your pool or spa water.

 

 

What is TDS?

TDS stands for “total dissolved solids” in water. It is composed of minerals and trace elements (iron, bromine, copper, etc.) and is measured in PPM. A high TDS level is often responsible for cloudy water, corrosion, scaling and algae growth. Finally, the TDS also has a great influence on the efficiency of disinfectants: the higher it is, the less efficient the treatment products will be. To keep your water healthy, we recommend investing in a TDS measuring solution.

What is the normal TDS value for my pool?

  • Bromine or chlorine pool: it is recommended to have a value between 250 and 2000 PPM
  • Salt pool: a value between 3000 and 5000 PPM (or 3 to 5g/l) is ideal.

What is the normal TDS value for my Spa ?

  • It is recommended to have a value between 600 and 2000 PPM with a maximum of 3000 PPM.

In conclusion: if your TDS is too high, your water is at risk of scaling and algae growth. If your TDS is too low, your equipment gets damaged and your eyes get irritated. There is no chemical solution to change your TDS value, only the renewal of water (the higher the TDS, the more you have to change it) can allow you to rectify the TDS of your water.
