VivaTest Swimming Pool & Spa Test Strips 3-in-1 – Fast & Accurate Water Testing (150 Strips)

VivaTest Swimming Pool & Spa 3-in-1 Test Strips help you check free chlorine, pH and total alkalinity in one simple water test. Compare the colour-changing pads with the chart on the bottle to get a practical overview of these three water-care measurements.

Designed for routine checks in chlorine-treated swimming pools, hot tubs and spas, these pool water test strips make it straightforward to monitor readings between treatments. The pack contains 150 test strips, with no electronic meter, batteries or calibration required.

Why choose VivaTest pool and spa test strips?

• Three measurements from one strip: check free chlorine, pH and total alkalinity together.
• Simple colour comparison: match each test pad with its corresponding row on the supplied chart.
• Quick water checks: colours develop within the stated 30–60-second reading window.
• 150 strips per pack: use a fresh strip for each routine check or follow-up test.
• No electronic equipment: no meter, batteries or calibration needed.
• Support for regular maintenance: use results alongside your pool or spa care instructions when deciding what to check or adjust.

What does this 3-in-1 water test measure?

• Free chlorine: checks the chlorine residual relevant to your sanitiser programme. Compare the result with the target specified for your system.
• pH: indicates how acidic or alkaline the water is. pH is relevant to chlorine performance and overall water balance.
• Total alkalinity: indicates the water's buffering capacity, which helps explain how readily pH can change.

Read all three results separately. An acceptable pH reading does not make up for insufficient sanitiser, and a chlorine result does not replace the need to check water balance.

Suitable uses

Use for routine water checks in chlorine-treated swimming pools, hot tubs and spas, including above-ground and inflatable pools maintained with an appropriate treatment programme. Follow the instructions for your equipment and treatment products.

These strips list free chlorine rather than a separate bromine measurement. For a bromine-treated spa, use a test explicitly labelled for bromine or confirm compatibility with the manufacturer of your exact strips.

How to use the test strips

Follow the instructions supplied with your bottle, including the required dip time, strip position and result-reading time.

1. With dry hands, remove one strip and close the bottle. Avoid touching the test pads.
2. Immerse the strip in a representative water sample for 2 seconds.
3. Remove it, gently shake off excess water and hold the strip horizontally.
4. Allow 30–60 seconds for the colours to develop, following the specified reading time for each pad.
5. Compare each pad with the matching parameter on the bottle's colour chart under suitable lighting.
6. Record the results and compare them with your pool or spa's operating targets.

Use a fresh strip for each test. If the supplied bottle or leaflet specifies different timings or handling, follow those instructions. For a fuller explanation of colour matching and common mistakes, read our pool and spa test strip results guide.

Important water-care information

These strips measure the three listed chemical parameters. They do not disinfect water, detect bacteria or confirm that water is free from infection risk. They do not provide separate readings for bromine, calcium hardness, cyanuric acid or salt concentration.

Colour matching provides an approximate result. Follow your equipment and treatment instructions, including chemical handling and bathing re-entry conditions. Use additional testing or advice from a pool or spa specialist when results are uncertain or problems persist.
