In-ground swimming pools are significant investments, and with winter fast approaching, it’s wise to start thinking about closing yours. Proper swimming pool maintenance will prevent your backyard oasis from being damaged by the freezing weather and make it easier for you to reopen it when spring comes.

Distinctive Swimming Pools, a leader in swimming pool maintenance in Washington, CT, discusses the steps you can take to properly close your pool:

• Adjust The Water Chemistry: Adjust the pool's water chemistry to prevent corrosion that may occur while the pool is not in use. The pH level should be from 7.2 to 7.6 and the alkalinity at 80 to 220 parts per million. Set the calcium hardness to 180 to 220. Then, shock the water by adding chlorine or another pool chemical to kill microorganisms.

• Reduce Water Level: Remove all accessories before shutting down your swimming pool. Lower the water level to between 12 and 18 inches below the skimmer if you're using mesh covers. If you're using floating covers, reduce the water between 3 and 6 inches below the skimmer.

• Drain All Equipment: Drain the pump, filters, chlorinators, and heaters and clean them before storing. If the filters cannot be removed, use a vacuum to get rid of the remaining water. You should also apply lubricants on your gas heaters before closing your pool.

• Clean The Pool & Winterize Plumbing: Brush the pool thoroughly to remove dirt and algae; this will keep your filters from clogging. After cleaning, drain the pipes to prevent them from freezing and bursting.

• Add Algaecide: Adding algaecide kills algae that cause the pool water to become discolored and smelly. Add algaecide when the chlorine level has returned to 1.0 to 3.0 ppm.
