Optimising Pool Water Levels and Chemistry for Summertime Heat

As temperatures rise in the summer, maintaining the perfect pool becomes increasingly challenging. High heat not only affects your comfort but also your pool’s water chemistry and water level through increased evaporation.
Understanding how to manage these changes effectively is key to ensuring your pool remains a safe and enjoyable place all summer long. Here’s the Spruce Pools guide to optimising pool water levels and chemistry during the hot months.

Managing Evaporation

Evaporation is a natural process that can lead to significant water loss in your pool during the summer. This not only affects water levels but can also concentrate chemicals, making the pool less comfortable and safe for swimmers.
Tips to Reduce Evaporation:
• Use a Pool Cover: This is the most effective way to reduce evaporation. Covering your pool when not in use can minimise evaporation by up to 95%. It also keeps debris out, reducing the need for cleaning and chemicals.

• Adjust Water Temperature: Keeping water cooler can slow evaporation rates. If you use a heater, consider lowering its temperature setting during peak heat times.

• Windbreaks: Wind significantly increases evaporation. Planting shrubbery or installing fences around your pool can help reduce the wind exposure.

• Optimal Pool Design and Location: If you’re planning a new pool, consider a location that minimises direct wind exposure and uses natural sun-shade patterns to keep the pool cooler.

Maintaining Optimal Water Chemistry

Hot weather can disrupt the delicate balance of your pool’s chemistry, promoting the growth of algae and bacteria and making the water irritating to skin and eyes.
Key Elements of Water Chemistry:
• pH Levels: The ideal pH level for pool water is between 7.2 and 7.8. High temperatures can cause pH levels to fluctuate more frequently. Test your water at least twice a week and adjust as necessary to maintain the correct balance.

• Chlorine Levels: Chlorine evaporates and degrades faster in high temperatures and under UV light. Ensure chlorine levels are maintained between 1-3 ppm. Consider using a stabilised form of chlorine that is less susceptible to UV degradation.

• Alkalinity: Maintain total alkalinity between 80-120 ppm to help buffer the pH and stabilise it against rapid changes.

• Calcium Hardness: Ideal levels are between 200-400 ppm. In hot weather, keeping calcium hardness in the correct range can prevent plaster damage due to aggressive water.

Advanced Tips:
• Regular Shock Treatments: Weekly shock treatments help keep the water clear of contaminants and assist in maintaining chlorine effectiveness.

• Cyanuric Acid: Also known as pool stabiliser, cyanuric acid helps protect chlorine from rapid UV degradation. Ideal levels should be between 30-50 ppm.

• Automated Chemical Feeders: These devices can help maintain consistent chemical levels, which is particularly helpful during long stretches of hot weather when manual testing and adjustment might not keep up with rapid changes.

Creating a Routine

Establishing a regular maintenance routine is crucial during the summer. Set a schedule to test water chemistry, add chemicals as needed, and adjust the pool cover. Regular checks will help you catch and adjust any imbalances quickly, preventing damage to your pool and ensuring it’s always ready for a refreshing swim.
By following these guidelines, you can optimise your pool’s water levels and chemistry, making your pool a refreshing escape from the summer heat, while also keeping maintenance needs in check.
