Six readings, taken at your pool — written down and sent to your phone before we drive away, including the weeks when the honest answer is that nothing needed adding.

Water chemistry

Chlorine is not one number, and it is not the number most people are shown. Free chlorine is what is left to sanitize; combined chlorine is what has already been used up and is what your eyes are stinging from.

Why the stabilizer reading decides everything

Cyanuric acid protects chlorine from sunlight, and it also holds it back. At 30 ppm a pool needs about 2 ppm of free chlorine to stay sanitary; at 100 ppm it needs nearer 8, and no amount of shocking fixes that — the only cure for high stabilizer is draining water. A company that never tests CYA will sell you chlorine for years without ever telling you why it keeps disappearing.

What the numbers do to each other

Low alkalinity makes pH bounce with every rain; high calcium hardness scales the heater exchanger before it clouds the water; pH above 7.8 costs you most of your chlorine's strength. They are one system. We write all six on the report so you can see which one moved.

What we will not do

We will not dose a pool we did not test, and we will not tell you the water is fine because it is clear. Clear and safe are different conditions and only one of them is visible.

The chat takes the symptom and the address, then hands it to the desk. It books visits — it never tries to diagnose a pool in a chat window.
