Fresno summers are legendary for their heat, with temperatures regularly exceeding 100°F from June through September. This extreme heat creates unique challenges for pool owners that require specific maintenance strategies. Here are the essential tips every Fresno pool owner should know.
Monitor Water Chemistry More Frequently
High temperatures accelerate chemical reactions in your pool water. Chlorine breaks down faster in intense sunlight and heat, leaving your pool vulnerable to bacteria and algae growth. During peak summer, test your water at least twice per week and adjust chemicals accordingly. Maintain free chlorine between 2-4 ppm and keep your pH between 7.2 and 7.6.
Combat Rapid Evaporation
Fresno pools can lose up to 2 inches of water per week during summer due to evaporation. This not only wastes water but concentrates minerals and chemicals, throwing off your water balance. Check your water level weekly and top off as needed. Consider a pool cover for when the pool isn't in use to reduce evaporation by up to 95%.
Increase Filtration Run Time
During summer, increase your filter run time to 10-12 hours per day. The combination of higher bather loads, increased debris, and warmer water temperatures means your filtration system needs to work harder. Run your pump during off-peak electricity hours (before 10 AM or after 8 PM) to save on energy costs.
Algae Prevention is Key
Warm water is algae's best friend. Maintain proper chlorine levels, brush your pool walls weekly, and consider using an algaecide as a preventive measure. If you notice any green tinge, act immediately—algae can take over a pool in just 24 hours in Fresno's heat.
Protect Your Pool Equipment
Heat can damage pool equipment too. Ensure your pump motor has adequate ventilation, check for unusual noises or vibrations, and keep the area around your equipment pad clear of debris. Consider a shade structure over your equipment to extend its life.
