Review: Simple, quick and accurate test kit. - Perfect test kit that gives you just the information you need to keep your pool balanced and clear. Easy and quick to read results. The bottle lasted two years, so great value.
Review: Simple - reliable - accurate pool test strips - These test strips seem to work much better and are far more accurate than other desertcart ones. The cheap bulk 6, 7 or more in one tests always seem to be all over the place and don't align with my pool company testing. These are a bit more expensive but a 50 pack will last thru the full season - vs throwing away half after 90 days with the larger packs. They are easy to read, the colors stand out and they are consistently accurate for my pool. Highly recommend!

## Questions & Answers

**Q: How do I use these pool test strips?**
A: Just dip and check—it’s that simple. Dip one test strip into your pool or spa water and remove it immediately. Hold the strip level (don’t shake off water) for 15 seconds, then compare the color pads to the chart on the bottle.

**Q: Do pool test strips expire?**
A: Yes, AquaChek pool test strips expire 18 months from the date of manufacture. To ensure accuracy, always check the expiration date printed on the top of the bottle cap before use. Using expired strips may result in incorrect readings.

**Q: Why are there 50 test strips in each bottle?**
A: Limiting the bottle to 50 pool test strips helps ensure you’re using fresh, accurate strips throughout the season—especially since water chemistry readings are most reliable when the strips are fresh.

**Q: Should I stock up on pool water test strips?**
A: If you're testing your pool once a week as recommended a single bottle of 50 Yellow test strips is more than enough to last an entire swim season. There's no benefit to overstocking. Keep your bottle sealed and stored properly, and you'll be covered.

**Q: How should I store the pool test strips?**
A: Keep the test strip bottle tightly closed in a cool, dry place, away from sunlight and moisture. Do not remove the desiccant packet inside—it helps preserve strip accuracy.
