Water Care: Total Dissolved Solids

SpaGuard productsIn every industry certain words or initials become commonplace and known by those who use them. That is also the case in the hot tub industry. Total Dissolved Solids (TDS) is one of these buzz words. Total Dissolved Solids means the amount of dissolved material in the water. This includes minerals, alkalinity, chloride, bromine, blood, sweat, and tears.

Everything you’ve ever put into this body of water.

When there are too many things hidden in your water, strange things can happen. Including…

  • Corrosion
  • Cloudy water
  • Eye irritation
  • Skin irritation
  • False readings on your testing strips

Adding chemicals is a large part of the issue because chemicals stay in hot tub water forever. So does everything else including body fluids. Why? Evaporation. Pure water comes out of your hot tub in the form of steam, leaving everything else behind. So, over time your TDS will increase.

With a hot tub, evaporation is significant because the water is warm and agitating when the jets are on.  In cool weather, you can actually see steam rising from the tub.

There are some products that can help remove some of the organic substances in your water. One of these is SpaPerfect™ which uses safe enzyme action to eliminate the bio elements in the water. Use once or twice per week. SpaPerfect™ is available at Clearwater Spas on the counter display.

Typically, you should drain your hot tub every 4-5 months, depending on which sanitizer you are using. This gives you a clean slate to begin again.

Be sure to test your water weekly. When I doubt, you can bring a water sample into Clearwater Spas to test your TDS. We’ll do it while you wait.
