How to Keep Your Pool Crystal Clear All Summer
San Diego summers mean long days by the pool — but the heat, sun, and increased usage can take a toll on water quality. Here's how to keep your pool looking its best all season long.
Run Your Pump Longer
During summer, your pool pump should run 8–12 hours per day to ensure proper circulation and filtration. Without adequate turnover, dead spots form where algae and bacteria thrive.
Pro Tip: Run your pump during off-peak electricity hours (before 10 AM or after 8 PM) to save on energy costs.
Test Water Chemistry Twice a Week
Summer conditions cause chemistry to fluctuate faster. Aim for these ranges:
| Parameter | Ideal Range |
|---|---|
| pH | 7.2 – 7.6 |
| Free Chlorine | 2 – 4 ppm |
| Alkalinity | 80 – 120 ppm |
| Cyanuric Acid | 30 – 50 ppm |
Shock Your Pool Weekly
Heavy use, sunscreen residue, and UV exposure deplete chlorine quickly. A weekly shock treatment oxidizes contaminants and restores sanitizer effectiveness.
Skim and Brush Regularly
- Skim the surface daily to remove leaves and debris
- Brush walls and tile weekly to prevent algae buildup
- Vacuum the floor at least once a week
Keep Your Filter Clean
A dirty filter can't do its job. Depending on your filter type:
- Cartridge filters: Clean every 2–4 weeks
- DE filters: Backwash monthly, full clean twice a year
- Sand filters: Backwash when pressure rises 8–10 PSI above normal
Watch Your Water Level
Evaporation increases dramatically in summer. Keep the water level at the middle of your skimmer opening for optimal circulation.
Consider a Professional Maintenance Plan
