Pool Water Testing and Chemical Balancing
Clear water isn't always safe water. We test your pool and add only what it needs, so the water is clean, easy on your skin and easy on your equipment.
Why Balanced Water Matters
Chlorine keeps germs and algae out. But chlorine only works well when the rest of the water is in balance too.
When pH is off, swimmers get red eyes and itchy skin. Water that stays out of balance can leave scale on tile, wear down the pool surface and shorten the life of your heater and salt cell.
Houston weather keeps changing the water. Sun and heat burn off chlorine. Big rains water it down. That's why we test every week.
What We Test
These are the common ranges pool pros aim for. We set yours based on your pool and your equipment.
| Test | Common range | Why it matters |
|---|---|---|
| pH | 7.4 to 7.6 | Off in either direction and swimmers get red eyes. It also changes how well chlorine works. |
| Free chlorine | 1 to 3 ppm | Kills germs and algae. Heat and sun use it up fast. |
| Total alkalinity | 80 to 120 ppm | Keeps pH from jumping around. |
| Calcium hardness | 200 to 400 ppm | Too low can eat at plaster. Too high leaves scale. |
| Stabilizer (CYA) | 30 to 50 ppm | Shields chlorine from the sun. Salt pools often run a little higher. |
| Salt (salt pools) | What your system calls for | Your salt cell needs the right level to make chlorine. |

FAQ
Chemical Balancing Questions
How often should pool water be tested?
At least once a week. In the summer heat, or after a big storm, the water can change in just a few days.
Why do my eyes burn after swimming?
It's usually not too much chlorine. Most of the time the pH is off, or the chlorine is used up and waste left in the water is causing it. A test tells us which.
What is chemical-only service?
We come once a week, test the water, add the chemicals it needs and empty the skimmer and pump baskets. You do the brushing, skimming and vacuuming.
Is a salt pool chemical free?
No. A salt pool makes its own chlorine from salt, but it still needs pH, alkalinity, calcium and stabilizer kept in range. Salt cells also need cleaning when scale builds up.
