Using Test Strips for Your Hot Tub: A Detailed Guide
Test strips are essential for maintaining the chemical balance of your hot tub water. They provide a quick and effective way to monitor hardness, bromine, chlorine, pH, and alkalinity levels, ensuring a safe and enjoyable soaking experience.
Benefits of Using Test Strips
Hot tub test strips are simple yet powerful tools for water maintenance. Here’s why you should consider using them:
- Ease of Use: Test strips are straightforward and require no advanced skills, reducing the likelihood of errors.

- Too Low: Can result in cloudy water and algae growth. Adjust with granular bromine or a floating dispenser.
- Too High: May damage spa covers, equipment, and skin.
- Recommended Range: 3.0–6.0 ppm.
-
Chlorine Levels:
- Use chlorine-specific strips to monitor levels.
- Recommended Range: 1.0–2.0 ppm.
-
pH and Alkalinity:
- Imbalanced pH: Causes scaling, corrosion, and foaming.
- Alkalinity acts as a buffer for pH.
- Recommended Ranges:
- pH: 7.2–7.8
- Alkalinity: 80–120 ppm.

- Difficult to Read the Color
- The Color Guide Is Not on the Bottle, so Be Careful
- If You Don’t Know How to Read a Pastel, It May Be an Issue
Editor’s review
The finest way to test the results is to take a bowl and dunk it down into the water about half of your hand’s duration and place the filled bowl on the table. Then immerse the strip in the bowl quickly, for half of a second and not 1 or 2 seconds. Doing more than half of a second will dilute the pads too and cast off the chemicals on the pads and you will get the erroneous color.
The most efficient problem is that the testing chart isn’t located at the bottle and not well laminated, but it’s far compact and easier to measure the strip on it. Eventually, after a few measurements, it’s far possible that the paper becomes wet, faded and ripped. Hence, it’s miles better to laminate the sheet and place it on your table.
