How to Choose the Right Test Kit
What Should You Test For?
At minimum, you need to test free chlorine and pH weekly. Beyond that:
- Total alkalinity — buffers pH and prevents wild swings
- Cyanuric acid (CYA/stabilizer) — protects chlorine from sunlight. Critical for outdoor pools
- Calcium hardness — prevents plaster/surface damage
- Total chlorine — the difference between total and free chlorine tells you if you have a chloramine problem
Strips vs Drops: Which Is Better?
Test strips are fine for routine weekly checks. They're fast, cheap, and good enough for maintaining a pool that's already balanced. But when you're troubleshooting a problem — green water, cloudy water, chlorine that won't hold — drop tests are significantly more accurate and show you exact numbers instead of color ranges.
The ideal setup is both: strips for quick weekly checks, and a drop kit for when something seems off.
Why the Taylor K-2006C Is #1
The K-2006C uses FAS-DPD testing for chlorine, which measures exact chlorine levels even at high concentrations (useful during shocking). Standard DPD tests max out and become unreliable above ~5 ppm. It also includes acid/base demand tests that tell you exactly how much chemical to add — not just that your pH is "high."
At $149 it's not cheap, but the reagents last for many tests and replacements are available individually. Pool service professionals use Taylor kits because the accuracy matters when you're responsible for someone else's pool.
When Digital Makes Sense
Digital photometers ($221+) eliminate the color-matching subjectivity of both strips and drop tests. If you have difficulty distinguishing colors, or you want to track exact readings over time, a digital tester pays for itself in precision. For most residential pool owners, though, a Taylor drop kit gives 95% of the accuracy at a fraction of the cost.
