Pool Chemical Balance Basics for Texas Pools
Understand chlorine, pH, alkalinity, calcium, and cyanuric acid so your Spring, TX pool stays clear, safe, and gentle on equipment.
Proper water chemistry protects swimmers and equipment. In Spring, TX, high evaporation and hard source water make balance especially important.
The Key Numbers
| Parameter | Ideal Range | Why It Matters |
|---|---|---|
| Free Chlorine | 1–3 ppm | Kills bacteria and algae |
| pH | 7.2–7.6 | Comfort + chemical effectiveness |
| Total Alkalinity | 80–120 ppm | Buffers pH swings |
| Calcium Hardness | 200–400 ppm | Prevents scale or plaster etching |
| Cyanuric Acid | 30–50 ppm | Protects chlorine from sunlight |
Common Local Challenges
- High CYA from repeated dichlor or trichlor use can lock chlorine and allow algae even when the test shows “chlorine present.”
- Rising calcium from evaporation concentrates minerals and can scale heaters and surfaces.
- pH drift is common after heavy rain or when aeration is high.
Testing Frequency
Weekly professional testing is ideal. Between visits, a simple test strip or kit helps you catch major swings. Never add large doses of multiple chemicals at once—adjust one parameter, wait, then retest.
