The Diagnostics of Pool Care
You cannot fix what you cannot measure. A Pool Test Kit is the single most important tool in a homeowner's arsenal because it dictates every chemical decision you make. Without accurate testing, adding chemicals is just guesswork—often leading to cloudy water, skin irritation, or wasted money on unnecessary products.

Understanding the Methods
Test kits primarily come in three forms: Test Strips (fast, dip-and-read), Liquid Drop Kits (highly accurate color matching), and Digital Testers (precise photometers). While strips are excellent for a quick "sanity check" before a swim, a liquid drop kit is essential for diagnosing algae blooms or calculating precise chemical dosages.

Why You Need This
Water balance fluctuates daily due to sunlight, rain, and swimmer load. A quality test kit allows you to catch pH drifts and sanitizer drops before the water turns green, saving you from expensive recovery treatments later.

Q: Are test strips as accurate as liquid kits?
A: Test strips are accurate enough for daily maintenance but can be difficult to read if you are colorblind or the lighting is poor. Liquid Drop Kits (specifically DPD methods) are generally considered more accurate and are better for troubleshooting specific problems like algae.

Q: What is the difference between OTO and DPD test kits?
A: OTO kits (yellow drops) only measure "Total Chlorine," which includes "dead" chlorine that can't kill bacteria. DPD kits (pink/red color match) measure "Free Chlorine," which is the active sanitizer available to clean the water. We always recommend DPD kits for accurate sanitation.

Q: How often should I test my pool water?
A: In the peak of summer, you should use test strips 2-3 times per week and run a full liquid drop test (including Calcium and Alkalinity) once a week.

Q: Do test kit chemicals expire?
A: Yes. Liquid reagents and test strips typically have a shelf life of 12-24 months. Heat and sunlight degrade them faster. If your drops are discolored or your results seem impossible, it is time to buy a Reagent Refill.

Q: My pH color is hard to match. What should I do?
A: Always read the result against a white background (like a piece of paper) and out of direct sunlight. If you consistently struggle with color matching, consider upgrading to a Digital Water Tester.
