Preparing The Pool For Winter
Preparing your above ground pool for winter in Minnesota is important. Cold weather and ice can cause damage if the pool is not ready. Taking the right steps helps protect the pool and makes opening easier in spring.
Start by cleaning and balancing the water. This keeps the water clear and prevents problems during winter. Next, lower the water level to avoid pressure on the pool walls from ice. Finally, protect your pool equipment to stop freezing and damage.
Cleaning And Balancing Water
Remove leaves, dirt, and debris from the pool. Use a net or vacuum for thorough cleaning. Test the water’s pH, alkalinity, and calcium hardness. Adjust chemicals to keep water balanced. Balanced water stops algae growth and protects pool surfaces.
Lowering Water Levels
Drain water below the skimmer and return jets. This prevents water from freezing inside and cracking parts. Avoid lowering water too much to protect the pool liner. Follow your pool manufacturer’s advice on the correct level.
Protecting Pool Equipment
Drain water from pumps, filters, and heaters. Store small parts indoors to keep them safe from cold. Cover equipment with waterproof covers to block snow and ice. Proper care of equipment extends its life and saves money on repairs.
Choosing The Right Winter Cover
Choosing the right winter cover is vital for your above ground pool in Minnesota. A good cover protects your pool from snow, ice, and debris. It keeps the water clean and safe during freezing months. Picking the right cover helps you avoid costly repairs in spring. Consider the material, size, and durability before buying.
Types Of Covers
Winter covers come in different types. Solid covers block all sunlight and debris. They prevent algae growth but need a pump to remove water on top. Mesh covers let water drain through but keep leaves out. They reduce water buildup but allow some sunlight. Safety covers are strong and support weight. They protect kids and pets from falling in. Choose a cover that fits your pool shape and size well.
Securing The Cover Properly
Securing the cover tightly is key. Use strong straps or cables around the pool frame. Make sure the cover is flat with no gaps. Check for loose areas after snow or wind. Tight covers stop debris and animals from entering. Add water bags or weights on the edges for extra hold. Proper securing extends your cover’s life and protects your pool better.
Preventing Ice Damage
Winter in Minnesota brings freezing temperatures that can harm your above ground pool. Ice can expand and crack the pool walls or liner. Preventing ice damage is key to protecting your pool during cold months. Simple steps help keep your pool safe and ready for spring.
Using Ice Absorbers
Ice absorbers soften the impact of freezing water. They reduce ice pressure on pool walls and liners. Place ice absorbers on the water surface before winter sets in. These devices help control ice formation and prevent cracks. They are easy to use and cost-effective for winter pool care.
Installing Air Pillows
Air pillows sit in the center of the pool water. They absorb the pressure caused by ice expansion. Installing air pillows creates a cushion between ice and pool walls. This reduces the risk of damage during freeze and thaw cycles. Air pillows are simple to install and highly effective in cold climates.

Maintaining Pool Water Chemistry
Maintaining the right pool water chemistry is key before winter. Balanced water prevents damage and keeps your pool ready for spring. It stops algae growth and protects pool surfaces and equipment. Proper care now saves time and money later. Follow these steps to prepare your above ground pool in Minnesota.
Adding Winterizing Chemicals
Start by adding winterizing chemicals to your pool water. These include algaecide, chlorine, and stain preventer. Algaecide stops algae from growing during cold months. Chlorine keeps bacteria and germs away. Stain preventer protects pool surfaces from discoloration. Follow the product instructions for the right amounts. Spread chemicals evenly in the water. Run the pump to mix everything well.
Testing Water Before Closing
Test your pool water before closing it for winter. Check pH, alkalinity, and chlorine levels. pH should be between 7.2 and 7.6 for balance. Alkalinity helps keep pH stable, aim for 80-120 ppm. Chlorine should be at a safe level to prevent germs. Use a reliable test kit for accurate results. Adjust chemicals as needed to reach proper levels. Testing ensures your pool stays clean and safe during winter.
Storing Pool Accessories
Storing pool accessories properly helps protect them from harsh Minnesota winters. It also makes reopening your pool easier in spring. Taking time to clean and store each item prevents damage and saves money. Organize accessories in a dry, sheltered place to keep them safe.
Removing And Storing Filters
First, turn off the pool pump and unplug the filter system. Remove the filter carefully and rinse off any dirt or debris. Let it dry completely to stop mold growth. Store the filter in a dry, cool area away from direct sunlight. Avoid stacking heavy items on top of the filter to keep it in good shape.
Safely Storing Ladders And Pumps
Detach the ladder from the pool and wash it with mild soap and water. Dry the ladder thoroughly to prevent rust or corrosion. Store it flat or upright in a dry place, away from moisture. For pumps, drain all water and clean the exterior. Keep pumps indoors to avoid freezing and damage during winter months.

Inspecting Pool And Equipment
Check the pool walls and liner for cracks or damage. Look closely at the filter, pump, and hoses. Replace any worn or broken parts. Make sure the pump runs smoothly without noise. Test the pool light and other accessories. Fix problems before filling the pool with water.
Cleaning And Refilling
Remove leaves, dirt, and debris from the pool cover and water. Use a pool vacuum or net to clean the bottom. Wash the pool walls with a soft brush to remove algae. Refill the pool slowly with fresh water. Balance the water chemicals to keep water safe. Check pH, chlorine, and alkalinity levels carefully.
