Texas Summer Pool Care: The 7 Habits That Keep Water Crystal Clear

Summers in North Dallas are brutal on residential pools. Surface temps climb above 95°F, evaporation accelerates, and chlorine demand can double overnight. Without a tight weekly rhythm, even a brand-new pool will turn cloudy or green in less than a week.

Below is the 7-habit checklist we run on every weekly route across Rockwall, Heath, Fate, Wylie, Plano, McKinney and the surrounding cities. None of it is exotic — but most homeowners skip 3 or 4 of these and pay for it in chemistry.

1. Brush before you skim

Brushing dislodges biofilm from walls and tile. Skim afterward to remove what you knocked loose. Doing it in the other order leaves debris baked onto the plaster.

2. Test free chlorine twice a week in July & August

Free chlorine should sit at 2.0–4.0 ppm. In peak heat, sanitizer can drop a full point per day. Testing twice catches the slide before algae shows up.

3. Keep cyanuric acid (CYA) under 60 ppm

CYA protects chlorine from UV burn-off, but too much makes chlorine sluggish. North Dallas tap water already carries traces — overstabilizing is the #1 reason owners report 'I add chlorine and nothing happens'.

4. Run the pump 8–12 hours per day

Cutting the pump to save electricity is the fastest way to grow algae. Variable-speed pumps let you run longer at lower wattage — usually cheaper than a short high-speed cycle.

5. Backwash or rinse the filter on schedule

Sand and DE filters: backwash when pressure rises 8–10 psi above clean baseline. Cartridge filters: rinse monthly, deep-clean quarterly. Skip this and circulation collapses.

6. Add stabilizer and shock at dusk, never midday

UV destroys un-stabilized chlorine in hours. Dosing at sunset gives the chemistry overnight to do its job before the next day's sun hits.

7. Photograph the equipment pad weekly

Snap a phone photo of the gauges and timer settings. If something drifts — pressure, salt level, leaks — you'll spot it before it becomes a $900 pump replacement.

When to call a pro

If your pool turns cloudy or green and home dosing isn't fixing it within 48 hours, the problem is usually circulation, CYA lock, or phosphates — not chlorine. A 30-minute diagnostic saves a $250 chemical spend.
