HTH Early Warning Test Strips 25-Pack

The HTH early Warning Test Strips 25-Pack is an essential diagnostic tool for maintaining chemical equilibrium in swimming pools and spas. These high-sensitivity strips provide immediate readings for four critical parameters: Free Chlorine, pH, Total Alkalinity, and Cyanuric Acid (Stabiliser). By identifying deviations early, users can prevent costly water treatments and protect pool surfaces from corrosive damage.

Ideal Use and Performance

• • 4-in-1 Simultaneous Testing: Evaluates four vital chemical levels on a single strip, reducing the time required for comprehensive water analysis.
• • Instant Results: Utilises "dip and match" technology that provides clear, colour-coded data in approximately two seconds.
• • Proactive Maintenance: Designed for weekly testing to catch "early warning" signs of chemical drift, helping to avoid algae blooms or cloudy water.
• • Universal Compatibility: Suitable for use in all pool types, including salt-water systems, chlorinated pools, and fibreglass or marblelite shells.

Safety Precautions

• • Moisture Protection: Always keep the container's pop-top lid tightly sealed and store the bottle in a cool, dry place to prevent humidity from ruining the sensitive test pads.
• • Handling Hygiene: Ensure your hands are completely dry before removing a strip from the canister; do not touch the reactive test pads with your fingers.
• • Proper Sampling: Dip the strip at least 15cm to 30cm below the water surface, away from return jets or chemical dispensers, for the most accurate representative sample.
• • Direct Sunlight: Avoid exposing the test strips to direct sunlight for extended periods, as UV rays can degrade the chemical indicators on the pads.

Frequently Asked Questions

• • How often should I test my water? It is recommended to test at least once a week during the swimming season, or more frequently after heavy rain and high swimmer loads.
• • Do the strips expire? Yes, check the expiry date on the bottom of the canister; expired strips will lose accuracy and may provide false readings.
• • Should I shake the strip after dipping? No, remove the strip from the water and hold it level for 15 seconds without shaking to allow the colours to develop correctly.
• • What is the ideal pH range for my pool? For most pools, aim for a pH between 7.2 and 7.6 to ensure swimmer comfort and chemical efficiency.

Clever Hack for pools

• • To ensure your test results are not skewed by surface-level debris or rainwater, use an empty, clean water bottle to collect a sample from "elbow depth" in the middle of the pool. Bring the bottle to a shaded area and dip your test strip into the bottle; this prevents the bright glare of the sun from making the colour-matching process difficult.
