Mondays Down Under – LaMotte, Water Testing, and Why Professional Testing Matters (Part 2)

Ask a question here

What separates a professional pool service company from someone simply adding chemicals?

In Part 2 of this special Mondays Down Under discussion, Lee Salisbury and Nick dive deeper into professional water analysis with the team from LaMotte, discussing why consistent, accurate testing is one of the biggest differences between average pool care and true water management.

The conversation explores the value of the WaterLink® Spin system, reducing user error, interpreting test results correctly, common mistakes professionals make after shocking a pool, and why understanding chemistry matters far more than simply reading numbers off a report.

Whether you're running a retail store, servicing residential pools, or maintaining commercial aquatic facilities, this episode is packed with practical advice that can improve both your water quality and your bottom line.

In This Episode

•  Why experience matters just as much as chemistry knowledge

•  Why professional testing equipment pays for itself 
•  Reducing user error with automated water testing 
•  The business case for investing in better testing equipment 
•  Saving time while improving customer service 
•  Comparing photometric testing to traditional reagent testing 
•  Why complete water analysis is more valuable than testing only chlorine and pH

•  Commercial pool testing 
•  Residential pool testing 

Common Testing Mistakes Discussed

•  Misinterpreting zero alkalinity after shocking a pool 
•  Understanding the effects of chlorine above 15 ppm 
•  Why high chlorine can produce misleading alkalinity readings 
•  Using high-range chlorine test strips for confirmation 
•  Running additional tests on the same high-chlorine sample 
•  Recognizing when the instrument is giving you an indicator—not a bad result 

Best Practices

•  Use professional-grade testing equipment

•  Verify unusually high chlorine levels before making chemical adjustments 
•  Store Spin Discs properly 
•  Reseal foil packaging after every use 
•  Protect discs from moisture and light 
•  Understand shelf life after opening 
•  Train technicians to recognize abnormal test patterns

Commercial Aquatic Facility Discussion

The episode also covers:

•  Daily health department testing requirements

•  Managing public pool safety 
•  Protecting swimmers through accurate testing 
•  Creating efficient testing workflows for aquatic facilities 

Key Takeaways

Professional water testing isn't about owning expensive equipment—it's about making better decisions.

Accurate testing saves time, improves customer confidence, reduces costly mistakes, and helps protect both swimming pools and the people using them. Understanding what your test results are actually telling you is every bit as important as obtaining the numbers themselves.
