Total Dissolved Solids

Total Dissolved Solids (TDS) is a measure of the total amount of all solids and other dissolved particles that are present in spa water. These can include minerals, salts, metals, and other substances that have dissolved in the water.

TDS can accumulate in spa water over time, often due to the use of chemicals, such as chlorine or bromine, or from the source water used to fill the spa. As TDS levels increase, the water can become cloudy or murky, and the effectiveness of spa chemicals may decrease.

The recommended TDS level for spa water is typically between 500 and 1500 ppm, although this can vary depending on the specific spa and its location. It is important to regularly test TDS levels and take appropriate action if levels become too high.

One method for reducing TDS levels in spa water is to drain and refill the spa with fresh water. This can help dilute the concentration of dissolved solids and restore proper water balance. It is also important to properly maintain spa chemicals and equipment to prevent TDS buildup and ensure proper water sanitation.

In addition to affecting water quality and chemical balance, high TDS levels can also cause damage to spa equipment and surfaces over time, so it is important to regularly monitor and manage TDS levels to maintain a safe and enjoyable spa environment.
