Plan your pool's winter closing chemicals. Calculate algaecide and shock amounts to ensure a clear opening in the spring. Taking the time to balance your water before the winter freeze prevents stains and saves you hundreds on startup chemicals next year.
Wait until the water temperature is consistently below 60°F (15°C). Algae struggles to grow in cold water, ensuring the pool stays clear until spring.
Never drain a pool completely! You only need to lower the water level below the skimmer and return lines to allow for proper plumbing blow-out and plugging.
Yes. A specialized winter algaecide or a long-lasting 'polyquat' helps provide an extra layer of protection as the chlorine levels naturally dissipate over the long winter months.
