Summer is officially here!
It’s time to fire up the barbecue and build new memories by the pool in your backyard.
As you inflate your pool mattress and dig up your kids’ pool noodles, remember that UV rays in sunlight and temperature changes increase the need to attend to your pool.
Both sunlight and temperature impact pool water chemistry and how the water behaves when it receives bathers.
While direct sunlight increases the sanitizer demand (chlorine and bromine) and evaporative loss on an uncovered swimming pool, temperature plays a much bigger role in both the sanitizer performance and the water loss through evaporation. For every 10° rise in temperature, approximately 50% more sanitizer is needed.
Warmer water also means a higher evaporation rate so you are expected to add more water to keep the pool properly topped off. This increases the need for chemicals to:
- Re-balance the water chemistry due to dilution and impurities in the new water added.
- Prevent known issues originating from the source water. High mineral or metal concentrations in your source water (municipal or well) can cause surface damage and buildups in the plumbing and equipment. If you have never had your source water tested for possible pool or hot tub problems, you may want to do so. There are analysis services available almost anywhere or you can purchase a test kit to measure iron, copper, manganese, calcium levels, and so on.
Three Simple Ways to Avoid Damage from Sunlight and Heat
When temperature rises, more attention is required.
- Set a routine schedule for water testing. Check your pool at least once a week and after each large bathing load to prevent pool chemical imbalance.
- Be consistent with how you test. Always secure your pool water samples from the same area of the pool, allowing for the filter pump to circulate at least one hour prior to gathering the water. And make sure you pull your pool water sample from approximately elbow’s depth, about 18 inches down from the surface and away from any return inlets where the water has gone through the system and returns back to the pool. Do not test the water right after chemicals have been added. Follow the guidelines from the product label to determine how long to wait before testing again.
- Cover your pool. Use a conventional cover or a chemical designed to act as a cover by increasing surface tension to slow down the water loss. Delaying evaporation can help keep your water chemistry in balance longer.
