Check your Pool Supplies
Check expiration dates on all pool chemical containers. Cleaning supplies that are past expiration should be properly disposed of and replaced with new chemicals. Also remember that if a chemical was not properly sealed before being stored in the off-season, you need to replace that as well.

Remove the Pool Cover
During the fall and winter months your pool cover accumulates water. Be sure to avoid mixing the water on the top of the cover with your pool water by using a pump or shop vacuum to remove the water from the top of the pool cover. After removing the cover, take it to a driveway or other solid place on a slant or slope for easier drainage. Thoroughly sweep and hose off the cover, and use cleaner or treatment if it’s recommended by the manufacturer of the cover.
