Maintaining proper water chemistry is critical when using a solar cover. Because the cover traps heat and chemicals, it can accelerate the degradation of the material if chlorine levels are too high. Always ensure your pool chemistry is balanced according to your pool professional's guidelines. Remove the cover during shock treatments to allow gases to escape, as excessive chemical concentration can damage the bubble structure and material integrity. Regular testing of your pool water ensures that the cover remains a helpful tool for heat retention rather than a liability. If you notice a strong chemical odor when removing the cover, this is often a sign that your water chemistry needs adjustment to protect both the pool equipment and the cover itself.

Proper Storage Techniques

When not in use, the cover should be stored in a shaded area, away from direct sunlight and extreme temperatures. Sunlight is the primary cause of material breakdown, so using a protective cover or a reel system that includes a sun-shield is highly recommended. Avoid leaving the cover bunched up on the pool deck, as the trapped heat can cause the material to warp or the bubbles to pop. If using a reel, ensure the cover is rolled evenly to prevent tension stress on the material. Proper storage during the off-season is equally important; clean, dry, and fold the cover carefully before placing it in a secure, cool, and dry location to ensure it remains ready for the next season.

Handling and Deployment

When deploying or removing the cover, avoid dragging it across rough surfaces or sharp pool coping, as this can cause tears or punctures. Utilizing a pool cover reel is the most effective way to manage the cover, as it minimizes physical handling and reduces the risk of accidental damage. If you must handle the cover manually, do so with a helper to ensure it is lifted rather than dragged. Be cautious of sharp edges around the pool perimeter.

Seasonal Inspection Routine

Perform a thorough inspection of your solar cover at the start and end of every season. Check for signs of brittleness, cracking, or widespread bubble loss, which are common indicators that the material has reached the end of its functional life. Examine all seams and edges for fraying or separation. If the cover shows significant signs of wear, it may no longer be effectively insulating the pool or preventing evaporation. Regular inspections allow you to catch small issues before they become major problems.
