The Problem Isn't You. It's How It Was Explained to You.

It's day two of the pool operator course. The instructor puts a problem on the board: a 75 by 35 foot pool, 4.5 feet average depth, raise free chlorine by 2 ppm. Everyone starts writing, and you're staring at the numbers.

You read that chapter last night. But the manual walks through each formula in paragraphs, a little differently every time, and nobody tells you where to start.

4 steps, always in order: knowns, formula, plug in, sanity check

In the book, every calculation sits on the same drawing: four boxes, always in order: knowns, formula, plug in, sanity check. That pool? About 88,600 gallons, so roughly 2.3 pounds of 65% cal hypo. Volume, turnover, dosing: the same four steps.

And every other topic gets its own page too: the circulation map, the centrifugal pump, free vs. combined chlorine, pH and the saturation index, cloudy water.

So when the next problem lands in front of you, you write down the knowns and work it through, without flipping back to the manual.

The Same Topic, Two Ways to Study It

  • The manual: line after line
  • Pumps and priming explained only in words
  • You walk into the exam unsure
Free available chlorine (FAC) comprises hypochlorous acid and hypochlorite ion, whose relative proportions are governed by pH according to the dissociation equilibrium of HOCl. Combined available chlorine (CAC) results from the reaction of free chlorine with ammonia and organic nitrogen compounds introduced by bathers, forming monochloramine, dichloramine and nitrogen trichloride. Total available chlorine is the sum of FAC and CAC. Breakpoint chlorination is achieved when sufficient free chlorine is added to oxidize the combined fraction completely, a dosage commonly estimated at approximately ten times the combined chlorine concentration.

One Page, One Topic, All Clear

Think of it this way:

The county inspector is at your pool. He checks the log, tests the water and asks: with pH at 7.8, how well is your chlorine actually working?

In the book you open the page on chlorine in water and see HOCl and OCl⁻ drawn side by side: at pH 7.5 about half your chlorine is the strong killer; at 7.8, only about a third.

pH range 7.0–7.8 (MAHC/CDC; many states 7.2–7.8) and the two closure limits: 6.5 and 8.0.

Same with the circulation map, the pump cutaway, the 4-step math, taking a water sample and cloudy water: each one on its own page.

Pool Operator Illustrated is 9 parts and 65 topics, all drawn, and it ends with every target range and every formula on one page, a full worked problem and the questions inspectors ask.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is this for me if I already work with pumps and filters?

Yes. The equipment pages go fast for you, and the book spends its time where most operators get stuck: chlorine chemistry, water balance and the math. It doesn't replace your course manual: it draws the same topics one per page and works every calculation in the same 4 steps, so you can review in order.

Where does the content come from?

It covers the topics taught in the main U.S. pool operator certification courses and in state or county operator courses, based on the CDC Model Aquatic Health Code (MAHC), CDC Healthy Swimming guidance, the Virginia Graeme Baker Act (CPSC) and OSHA Hazard Communication. State rules differ on some numbers, like the pH range or how often you test, so every range, interval and limit is marked to check against the code your state or county enforces.

Is this official material?

No. It's an independent illustrated study book. It isn't affiliated with or endorsed by PHTA, NRPA, the CDC or any health department or certification body.

Does it replace the certification course?

No. You still take the course and exam your health department requires, and your certificate comes from that course, not from this book. The book doesn't give a certificate or continuing-education credits. It helps you understand the course and review it, one topic per page.

Are the practice questions the ones on the exam?

No. They're exam-style questions written for this book, with every answer explained. They aren't official questions from any exam.

When and how do I get it?

The book and the 2 bonus books come as PDFs by email, to the address you enter at checkout.

Do I have to pay every month?

No. It's a one-time payment.

Can I have it on paper?

Yes. The PDFs are ready to print, so you can keep a copy in the pump room.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.
