Key Water Testing Methods

Overview

• Multiple methods can be used, no need to rely on just one
• Choice based on factors like time of year, type of test needed

Test Strips

• Pros: Fast, affordable (though prices have increased), good for quick checks
• Cons:
  • Subjective, color interpretation varies
  • Total hardness (not just calcium hardness)
  • Best for quick checks and double-checking other tests
• Uses: Great for hot tubs, spas, and when in a hurry
• Variety: Available for different tests like phosphates, salinity, copper, iron

Reagent Test Kits

• Pros: Accurate, good sample size for color matching
• Cons: Time-consuming compared to test strips
• Popular Option: Taylor Test Kits (NSF certified)
  • Models: K206 and K205
• Usage Advice: Reagents expire, replace yearly

Photometers

• Pros: Extremely accurate digital readouts
• Popular Brands: Lamont Color Q series, Spin Touch
  • Spin Touch: High-end, efficient
• Usage:
  • Uses tablets - longer shelf life
  • Highly accurate, great for commercial pools
