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
