The pool & hot tub test strips highlight, chlorine & bromine levels, the water's pH and Total Alkalinity levels. There are three separate sections on each strip to indicate each individual level. Chlorine levels of a hot tub should be 3‑5 ppm (Parts Per Million), bromine levels should be 6-10 ppm, pH levels should be 7.2 ‑ 7.6 and Total Alkalinity levels should measure 80 ‑ 120 ppm (Parts Per Million).Chlorine levels of a pool should be 1-3 ppm (Parts Per Million), pH levels should be 7.2 ‑ 7.6 and Total Alkalinity levels should measure 80 ‑ 120 ppm (Parts Per Million).

Using the testing strips to check water balance enables you to identify what chemicals need to be added to bring them within the correct parameters. Untested water can become a breeding ground for bacteria or develop a chemical imbalance that makes eyes and irritate skin.

How often should I test my pool or spa water?

For best results, test swimming pool and hot tub water at least 2–3 times per week and always after heavy use, rainfall, or adding treatment chemicals.

Why is it important to test chlorine and pH levels?

Maintaining the correct chlorine and pH levels helps keep water clean, clear, and comfortable while supporting the effectiveness of your pool or spa sanitiser.
