Pool Test Kit for Pool Water Testing

The HTH™ 6-Way Pool Test Kit is a liquid drop-test pool test kit that measures the six chemistry levels every pool owner needs to track.

  • Tests 6 key levels: free chlorine, total chlorine, bromine, pH, total alkalinity, calcium hardness, and cyanuric acid
  • Works in chlorine, bromine, and saltwater pools
  • Includes solution for up to 100 pool water tests
  • Test 2-3 times per week to catch problems early
  • Collect water 18 inches below the surface for accurate readings
  • Store cool and dark, replace yearly

Product Benefits

Comprehensive 6-Level Testing

Drop-test reagents measure free chlorine, total chlorine, bromine, pH, total alkalinity, calcium hardness, and cyanuric acid. These are the six parameters that keep your water safe, balanced, and comfortable for swimmers.

Accurate Liquid Reagent Method

Drop tests are more precise than test strips for routine maintenance and troubleshooting. Use this swimming pool test kit at pool opening and closing. It's also useful any time test strip results seem off or you need to verify a chemistry problem.

Easy Storage

Compact and durable design; store in a cool, dark place and replace yearly

Works in Every Pool Type

Compatible with chlorine, bromine, and saltwater pools. It doubles as a salt pool test kit, though it does not test salt (NaCl) levels directly. Use a dedicated salt strip or meter for that.

How to Use

1. Collect a Water Sample

Go approximately 18 inches below the water surface (deep enough so the water reaches your elbow).

2. Dispense Drops into Water Sample

Hold the bottle vertically while dispensing.

3. Adjust Chemicals as Needed

Use your test results to balance the chemicals in your swimming pool water.

4. Repeat Weekly

Test and balance swimming pool water two or more times weekly.

Ingredients

Active Ingredient: - Sulfuric acid: 0.1-1% w/w (less than 1% by weight)

Other Ingredients: - Solution purified with water

DANGER: May be corrosive to metals. Causes severe skin burns and serious eye damage.

Frequently Asked Questions

  • What does the 6-Way Pool Test Kit test for?

    The HTH™ 6-Way Test Kit tests for free chlorine, total chlorine, bromine, pH, total alkalinity, calcium hardness, and cyanuric acid (stabilizer). These are the six most important parameters for maintaining safe, clear, and balanced pool water.

  • How often should I test my pool water?

    Test your pool water at least 2–3 times per week during swim season. Test more frequently after heavy rain, a large number of swimmers, adding chemicals, or at pool opening and closing. Regular testing prevents problems before they become costly.

  • What are the ideal chemical levels for a pool?

    Target these ranges: Free Chlorine 1–4 ppm, pH 7.2–7.6, Total Alkalinity 80–120 ppm, Calcium Hardness 200–400 ppm, and Cyanuric Acid 30–50 ppm. Keeping all parameters in range ensures sanitizer effectiveness and swimmer comfort.

  • How do I use the 6-Way Test Kit?

    Fill the test vial to the indicated line with pool water, add the appropriate reagent drops for each test, cap and invert to mix, then compare the color to the chart on the kit. Test away from direct sunlight for the most accurate color reading.

  • Is the 6-Way Test Kit accurate for saltwater pools?

    Yes, this test kit is compatible with both chlorine-based and saltwater pools. Note that it does not test salt (NaCl) concentration — use a dedicated salt test strip or meter if you need to verify salt levels in a saltwater pool.

  • How do I know what chemicals to add after testing my pool?

    Compare your results to the ideal ranges. If chlorine is low, add sanitizer or shock. If pH is off, add pH Up or pH Down. For low alkalinity, add Alkalinity Increaser. For low calcium hardness, add Calcium Hardness Increaser. For low CYA, add Chlorine Stabilizer.

  • How do I adjust pool chemicals based on test results?

    Always adjust chemicals one at a time, starting with alkalinity, then pH, then calcium hardness, then chlorine/stabilizer. Wait 4–6 hours between adjustments and retest before adding the next chemical to avoid overcorrecting.
