Pool Treatment Course

Lesson 1 • pH: The Master Variable

Explains the pH scale, its logarithmic nature, and its effect on all other chemical parameters. Establishes pH as the central control point for pool treatment decisions.

Lesson 2 • Water as a Chemical Medium

Covers water's molecular properties and its role as a solvent in pool systems. Connects basic chemistry to why pools require active chemical management.

Lesson 3 • Calcium Hardness and Saturation

Introduces calcium hardness as a structural water parameter affecting surfaces and equipment. Links hardness to scaling and corrosion risk in pool systems.

Lesson 4 • Alkalinity and Its Role

Defines total alkalinity as pH's stabilizing buffer and explains its relationship to pH drift. Students connect alkalinity management to consistent water balance.

Lesson 1 • Combined Chlorine and Chloramines

Identifies chloramine formation from nitrogen compounds and its impact on sanitizer effectiveness. Students learn to detect and eliminate combined chlorine through breakpoint chlorination.

Lesson 2 • Cyanuric Acid and Chlorine Stabilization

Explains cyanuric acid's role in protecting chlorine from UV degradation and its trade-off with sanitizer speed. Establishes safe cyanuric acid concentration limits.

Lesson 3 • Why Pools Require Sanitization

Establishes the public health rationale for continuous pool disinfection. Connects microbial risk to the need for residual sanitizer maintenance.

Lesson 4 • Chlorine Product Forms and Selection

Compares liquid, granular, and tablet chlorine products by strength, stabilization, and application method. Enables informed product selection for different pool types.

Lesson 1 • Professional Lab Analysis

Explains when to send water samples to a certified laboratory and how to collect samples correctly. Connects lab results to comprehensive treatment planning.

Lesson 2 • Overview of Pool Water Parameters

Identifies all standard parameters requiring routine testing and their acceptable ranges. Provides a complete testing framework before introducing individual methods.

Lesson 3 • Digital and Electronic Meters

Introduces photometers, ORP meters, and multiparameter probes for precise measurement. Covers calibration, maintenance, and interpretation of electronic readings.

Lesson 4 • Test Strip Methods

Covers test strip use, reading technique, and common sources of error. Students understand strips as a rapid screening tool with inherent accuracy limitations.

Lesson 1 • Saltwater Chlorine Generation

Explains electrolytic chlorine generation from salt and its operational requirements. Students understand that saltwater pools still rely on chlorine as the active sanitizer.

Lesson 2 • Bromine as a Pool Sanitizer

Covers bromine chemistry, its stability at higher pH, and its preference for spas and indoor pools. Contrasts bromine with chlorine across key performance parameters.

Lesson 3 • Mineral and Biguanide Systems

Covers copper-silver mineral systems and biguanide as chlorine-free alternatives with specific compatibility rules. Students identify appropriate use cases and incompatibilities.

Lesson 4 • Oxidation as a Complementary Process

Distinguishes oxidation from sanitization and explains how oxidizers destroy organic waste. Connects regular oxidation to reduced chlorine demand and clearer water.

Lesson 1 • Hydraulic Balance and Flow Optimization

Addresses flow rate, pressure readings, and variable-speed pump programming for efficiency. Connects hydraulic performance to chemical distribution and energy savings.

Lesson 2 • Cartridge Filtration Systems

Explains cartridge filter construction, cleaning methods, and replacement criteria. Connects cartridge maintenance to consistent water clarity and flow.

Lesson 3 • Sand Filtration Systems

Covers sand filter operation, backwashing procedure, and media replacement intervals. Students understand sand filtration's role in removing suspended particles.

Lesson 4 • Circulation System Fundamentals

Explains how pumps, pipes, and returns distribute treated water throughout the pool. Establishes circulation as the delivery mechanism for all chemical treatment.

Lesson 1 • Dosing Calculations and Adjustments

Applies product label data and pool volume to calculate precise chemical doses. Students practice raising and lowering each parameter to target range.

Lesson 2 • The Langelier Saturation Index in Practice

Applies the Langelier Saturation Index to assess overall water balance and predict scaling or corrosion. Students calculate LSI and adjust parameters to reach equilibrium.

Lesson 3 • Calculating Pool Volume

Teaches volume calculation formulas for rectangular, circular, and irregular pool shapes. Accurate volume is the foundation for all dosing calculations in this chapter.

Lesson 4 • Shock Treatment Procedures

Covers the purpose, types, and correct execution of pool shock treatments. Students distinguish between chlorine shock and non-chlorine shock applications.

Lesson 1 • Mustard and Black Algae Treatment

Addresses the more resistant mustard and black algae with aggressive brushing and targeted chemical protocols. Emphasizes equipment decontamination to prevent reintroduction.

Lesson 2 • Green Algae Treatment Protocol

Provides a step-by-step remediation sequence for green algae outbreaks using shock and algaecide. Students execute the full treatment cycle from diagnosis to clear water.

Lesson 3 • Understanding Pool Algae

Identifies the three main algae types by color, growth pattern, and treatment difficulty. Establishes why algae thrive when sanitizer and circulation are inadequate.

Lesson 4 • Algaecide Chemistry and Selection

Covers quaternary ammonium, copper-based, and polymer algaecides and their appropriate applications. Students match algaecide type to algae species and pool conditions.

Lesson 1 • Scaling and Calcium Deposits

Addresses calcium carbonate and calcium silicate scale formation on surfaces and equipment. Students apply descaling treatments and adjust water balance to prevent recurrence.

Lesson 2 • Cloudy Water Diagnosis and Treatment

Identifies the four main causes of cloudy water and maps each to a specific corrective action. Students use a diagnostic checklist to isolate the root cause efficiently.

Lesson 3 • High Cyanuric Acid and Dilution

Explains the consequences of excessive cyanuric acid and the limited options for reduction. Students calculate partial drain-and-refill volumes to restore acceptable levels.

Lesson 4 • Staining and Discoloration Issues

Covers metal-based and organic staining, their identification, and targeted removal treatments. Students distinguish stain type before applying chemical or physical remediation.
