## Questions & Answers

**Q: How do I use these test strips?**
A: Just dip and check—it’s that simple. Dip one 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 Select Connect kit.

**Q: Do test strips expire?**
A: Yes, AquaChek 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 strips in each bottle?**
A: Limiting the bottle to 50 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 test strips?**
A: We don't recommend stocking up. If you're testing your pool once a week as recommended, a single bottle of 50 test strips is more than enough to last an entire swim season. Accurate results require fresh strips.

**Q: Do you have any tips for keeping the strips fresh and accurate?**
A: Yes! Only put dry fingers into the bottle. Take one strip out at a time, then close the bottle immedialty. Keep the bottle tightly closed in a cool, dry place, away from moisture. Do not remove the desiccant packet inside, it helps preserve strips.
