Luis has been on our pool every Thursday for two years. The report is on my phone before his truck is out of the driveway, and I finally understand why the chlorine kept vanishing: stabilizer was at 90. They told me to drain a foot instead of selling me more shock.

Pool water testing in Winter Park
Clear and safe aren’t the same thing. Six numbers tell you which one you have.
Signs you need it
When to call about water testing
Chlorine keeps disappearing
Almost always the stabilizer holding it back.
Eyes sting after a swim
That’s combined chlorine, the used-up kind, not too much chlorine.
Cloudy after every storm
Low alkalinity lets pH bounce with every rain.

How we do it
The honest version of water testing
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.
What the numbers do to each other
Low alkalinity makes pH bounce with every rain; high calcium hardness scales the heater before it clouds the water; pH above 7.8 costs you most of your chlorine’s strength. They are one system, so all six go on the report and you can see which one moved.
What we will not do
We won’t dose a pool we didn’t test, and we won’t tell you the water is fine because it is clear. Clear and safe are different conditions, and only one of them is visible.
Step by step
What happens on the visit
Test six
Free and combined chlorine, pH, alkalinity, calcium and stabilizer.
Find which moved
One reading out of range usually explains the others.
Dose to the reading
Only what the numbers call for, logged by amount.
Write it down
All six, with the range each should be in.
What it costs
What decides the price
No surprise lines. Every job is quoted in writing, and nothing is done until you reply.
What we look at
- Testing is part of every weekly visit
- A one-off water panel comes with the $89 filter clean
- Chemicals are listed by amount on every report
How you’re quoted
In writing, with the reading or the pressure that made us recommend it. Approve all of it, some of it, or none of it.
A partial drain for high stabilizer is quoted in writing on the visit that finds it, never slipped in.
Reviews
What customers say about our water testing
Honest about the salt cell. It had one more acid wash in it, so that is what they did. When it did need replacing a year later, the quote came in writing first.
Straight answers
Water testing: questions
Why does my chlorine keep disappearing?
Nine times out of ten it is stabilizer (cyanuric acid). It protects chlorine from the sun and also holds it back, so a pool at 80 ppm needs roughly three times the free chlorine of a pool at 30. More chlorine won’t fix it; replacing some water will.
The water is clear. Is it fine?
Clear and safe are different conditions, and only one of them is visible. A pool can be perfectly clear with no free chlorine left in it, and cloudy after a storm with nothing wrong. That is why we write the numbers down.
What are the six readings?
Free chlorine, combined chlorine, pH, total alkalinity, calcium hardness and cyanuric acid (stabilizer). Together they say whether the water is safe, comfortable and kind to the equipment.
