Total Dissolved Solids (TDS) are the measure of everything that has dissolved in the water over time from numerous chemical dosages. High TDS contributes to cloudy water, makes balancing chemicals more difficult and can lead to increased chlorine usage. Test the TDS to find out if it is time to drain and refill a hot tub.
Get test results in seconds with just one dip! Dip an AquaChek TDS strip in your pool or spa water for one second and remove it immediately.
For a clean and healthy pool, test the water at each end a minimum of twice a week!
*Note: a minimum of 2 bottles of strips must be ordered
