Yes! When the pool water temperature drops, you tend not to use the pool as much, which means there is less need for chlorine. During that time, you may want to turn your FROG® dial setting down so it puts less chlorine in the water.
In addition, when pool water gets cold, the chemical reactions slow down. Chlorine is extremely effective in temperatures as low as 65°F and as high as 99°F. Below 65°F, chlorine’s effectiveness begins to decline.
During the cooler spring and fall months of pool operation, it’s important to test and adjust your water balance and chlorine levels regularly with FROG Test Strips. Fall’s beautiful foliage may result in more leaves in your pool, which can also cause problems. Make sure to clean out your skimmer basket more often to keep your water quality under control.
