Enjoy total peace of mind every time you step into your hot tub, knowing your water is safe, balanced and ready to relax in. ClearWater 4-in-1 Test Strips take the guesswork out of spa care, giving you lab-accurate readings in just 15 seconds so you can spend less time worrying about water chemistry and more time actually enjoying your hot tub.
ClearWater strips are made by the original founders of dip testing, and are trusted for some of the most accurate at-home readings on the market. Each of the 50 strips in this pack is calibrated to detect four key water parameters in a single dip — no separate test kits, no mixed-up readings, just a fast colour-match against the scale on the pack. Every strip is backed by ClearWater's proven quality guarantee, so you can trust the result you're looking at.
What does each test strip actually measure?
- Chlorine (ideal range: 3–5 ppm)
- Bromine (ideal range: 6–10 ppm)
- pH (ideal range: 7.2–7.6)
- Total Alkalinity (ideal range: 80–120 ppm)
How long does it take to get a reading?
Just 15 seconds. Dip the strip, hold it level without shaking, and match the colours against the pack's scale — no waiting around, no lab equipment, no complicated calculations.
How do I use ClearWater 4-in-1 Test Strips?
- Remove one strip, keeping the rest of the pack dry
- Dip into the water for a couple of seconds
- Hold level for 15 seconds — don't shake
- Match the strip against the colour scale on the pack
No equipment, wiring or setup is needed — these strips work straight out of the pack.
- Pack size: 50 strips (approximately 50 individual tests)
- Also available in: 25 Strips and 150 Strips, if you need a smaller or larger supply
- Reads: chlorine, bromine, pH and total alkalinity in one dip
- Result time: 15 seconds
Is this suitable for both hot tubs and pools?
Yes — ClearWater 4-in-1 Test Strips work equally well for hot tub and pool water, making them ideal for regular residential hot tub maintenance as well as garden and holiday-home pools. Testing weekly (or after heavy use) helps prevent cloudy water, bacteria growth and unnecessary strain on your hot tub's filtration system before it becomes a bigger problem.
