Balance the Water Chemistry

Before closing your pool, it’s crucial to balance the water chemistry about a week before you plan to shut it down. This includes adjusting the pH levels to between 7.2 and 7.6, alkalinity between 80 and 120 ppm, and calcium hardness around 180 to 220 ppm. Proper water chemistry prevents corrosion and scale buildup, which are critical concerns for fiberglass pools.

Thoroughly Clean the Pool

Remove any leaves, dirt, and debris from the water. Scrub the sides and bottom of your fiberglass pool to prevent algae buildup and staining. Ensure your pool’s filter system is also cleaned and free from debris to maintain proper function throughout the winter.

Lower the Water Level

For fiberglass pools, lowering the water level is generally recommended to just below the skimmer. This helps protect the skimmer and plumbing from freezing and potential damage. Consult your pool manufacturer’s guidelines for specific recommendations related to your pool model.

Add Winterizing Chemicals

Use a winterizing chemical kit suited for fiberglass pools to help keep the water clean and clear throughout the off-season. These kits typically include algaecide and a slow-releasing sanitizer to prevent algae growth and maintain water quality.

Protect Your Equipment

Drain all water from your pool pumps, heater, filters, and plumbing. Any water left in the equipment can freeze and cause cracking or other damage. After draining, store detachable equipment indoors to protect it from the elements.

Cover Your Pool

Invest in a high-quality pool cover specifically designed for fiberglass pools. Ensure the cover fits snugly and securely, as this will prevent debris from entering the pool and will also help manage water chemistry balance over the winter months.

Inspect and Repair

End the season by inspecting your pool for any signs of damage or wear, such as cracks, leaks, or surface degradation. Addressing these issues before the winter can prevent further damage due to freezing temperatures and moisture.

Professional Inspection

If you’re unsure about any steps in the maintenance process or want to ensure your pool is as protected as possible, consider hiring a professional. A professional can provide a thorough inspection and perform any necessary repairs before the cold weather sets in.

By following this year-end pool maintenance checklist, you’re not only extending the life of your pool but also making your life easier when it’s time to reopen your pool in the spring. Remember, taking the time to properly close your pool will save you time, money, and effort when warmer days return.
