from our friends at Orenda
As the water temperature rises, so too does the sanitizer demand. Not only are living organisms more active in warmer temperatures, but most chemical reactions–in pools, anyway–occur faster in warmer water too. Below 55ºF, sanitizer demand is much less than say, 85ºF. I say this from personal experience.
We cannot ignore sanitization below 55º, but let’s be honest. Keeping a pool algae-free in the winter is much easier than in the summer. I’m here to tell you that temperature is a major reason why.
As water temperature declines, so too does the speed of chemical reactions. Take for example an Orenda product like CV-600 enzyme. Enzymes are reactive beginning at approximately 65ºF. Below 65, they slow down and go dormant. It is also difficult to dissolve chemicals like calcium or sodium bicarb in cold water. Read More
