What you'll learn in this module
Each chapter below corresponds to one lesson. Links marked with → take you into our reference library for a deeper write-up on the same topic.
- 01Water Balancing Basics (pH, Alkalinity, Calcium)
The three big numbers every tech tests first. Ranges, why they matter, quick fixes.
Open → - 02Sanitizers and Disinfectants (Chlorine, Bromine, Alternatives)
How each sanitizer works, when to use which, and the myths to stop repeating.
Open → - 03Algae Prevention and Treatment in Tropical Climates
Green, black, mustard — what each one is, how Florida humidity helps it, how to win.
Open → - 04Stain and Scale Control (Florida Minerals)
Florida fill water is hard. Here's how to prevent metal stains and calcium scale.
Open → - 05Testing Methods and Tools (Kits, Digital Testers, Records)
Drop kits, strips, digital meters — which is accurate, which is fast, and how to record.
Open → - 06Cyanuric Acid (CYA) Management
CYA protects chlorine — but too much creates 'chlorine lock.' How to stay in range.
Open → - 07Shock Treatments: When, How, Alternatives
Why half-shocking makes things worse. Breakpoint math, timing, non-chlorine alternatives.
Open → - 08Phosphate Control and Nutrient Reduction
Phosphates don't hurt swimmers — they feed algae. When removal is worth it.
Open → - 09ORP and Automation Systems for Monitoring
What ORP actually measures, how commercial automation reads and responds.
Open → - 10Seasonal Adjustments (Rain, Heat, Hurricanes)
Florida's weather swings water chemistry hard. How to adjust by season.
