Why Pool Water Testing Is Essential

Regular pool water testing helps maintain swimmer safety, prevents algae and bacteria growth, protects your pool surfaces and equipment, and saves money by avoiding unnecessary chemical use. For best results, test your water two to three times per week, especially after storms, heat waves, or heavy pool use.

What to Test For and Why It Matters

Monitoring your pool’s chemistry is critical for water balance and clarity. Here are the key elements to test:

  • pH (7.4 – 7.6): Controls comfort and supports effective chlorine function

  • Free Chlorine (1.0 – 3.0 ppm): Kills harmful microorganisms

  • Alkalinity (80 – 120 ppm): Buffers pH to prevent sudden swings

  • Calcium Hardness (200 – 400 ppm): Protects surfaces and equipment from scaling or corrosion

  • Cyanuric Acid (30 – 50 ppm): Protects chlorine from UV rays in outdoor pools

  • Total Dissolved Solids (under 1500 ppm): Helps maintain overall water clarity and chemical effectiveness

Your Pool Water Testing Options

There are several ways to test your pool water, depending on your preferences and accuracy needs:

  1. Test Strips – Quick and beginner-friendly; great for daily spot checks

  2. Liquid Drop Kits – More precise; ideal for weekly or deep analysis

  3. Digital Testers – Highly accurate and often app-compatible

  4. Professional Testing – The most reliable option; contact Mago Pools LLC for a free expert analysis and custom recommendations

How to Collect a Proper Water Sample

To get an accurate reading, use a clean plastic container. Collect the sample from 12 to 18 inches below the surface, away from skimmers or return jets. Test the water within two hours.

Common Water Issues and Solutions

  • Cloudy water: Often due to low chlorine or high TDS

  • Green water: Algae growth requires shocking and brushing

  • Irritated eyes or chlorine odor: Caused by chloramines—shock treatment is recommended

  • White scale buildup: Indicates high calcium hardness or pH imbalance

If you’re unsure where to start, our team provides on-site pool maintenance services to help get your water balanced and clear.
