Summer is the perfect time to enjoy your swimming pool, but hot weather can make pool maintenance a challenge. High temperatures, increased swimmers, and UV exposure can affect your pool’s water balance, leaving it cloudy or prone to algae. In this guide, The Spa Shop will walk you through keeping your pool chemicals in check during the summer months.

Why Summer Changes Pool Chemistry

1. Increased Evaporation – Heat causes water to evaporate, concentrating chemicals like chlorine and affecting pH.

2. More Swimmers – Sunscreen, sweat, and body oils increase contaminants, requiring more sanitizer.

3. UV Breakdown – Sunlight can break down chlorine faster, meaning your pool may need more frequent dosing.

Key Chemicals to Monitor

1. Chlorine (Sanitizer)

Chlorine keeps your pool free from bacteria and algae. In summer, check your levels daily and aim for 1–3 ppm. At The Spa Shop, we recommend Power Chlor, a reliable sanitizer that works effectively even in high temperatures.

2. pH Levels

High temperatures and evaporation can raise your pH. Ideal pH is 7.2–7.6. A pH too high reduces chlorine effectiveness, while too low can irritate skin and eyes. 

3. Alkalinity

Alkalinity acts as a buffer for pH, keeping it stable. Target 80–120 ppm. Adjust with alkalinity increasers or decreasers as needed.

4. Calcium Hardness

Hot water can increase calcium saturation, leading to scaling. Keep levels at 200–400 ppm to protect pool surfaces and equipment.

5. Specialty Chemicals

• Algae Prevention: Use BioGuard AlgiGuard to prevent green or cloudy water before it starts.

• Stabiliser: Add BioGuard Stabiliser to protect chlorine from UV breakdown, keeping your pool safe longer.

• Filter Cleaning: Keep your pool filter running efficiently with BioGuard Filter Brite, which cleans and restores filter performance for clearer water.

Tips for Balancing Your Pool in Summer

1. Test Water Frequently – During heatwaves or heavy use, test your pool at least 2–3 times a week. Or, bring a sample to The Spa Shop for a free professional water test.

2. Add Chemicals Gradually – Avoid shocking the pool too often; small adjustments are safer.

3. Run Your Pump Longer – Circulation helps distribute chemicals evenly, especially in hot weather.

4. Keep Your Pool Covered – A cover reduces evaporation, slows chlorine loss, and keeps debris out.

5. Maintain Filters – Clean your filter regularly using BioGuard Filter Brite to ensure clear, healthy water.
