Bubble Solar Cover for Rectangular Pools Blue 3 x 4 m (10 x 13 ft) Keep your rectangular pool cleaner and easier to maintain with a durable bubble solar cover designed for outdoor pools. The bubble design captures solar energy while providing a dustproof layer over the water surface, helping limit debris and reduce evaporation. Key benefits Dust and debris protection: Creates a protective barrier that keeps leaves, dirt, and airborne debris off the water surface for less skimming and filtering. Heat retention and evaporation reduction: The bubble surface is designed to help limit heat loss and reduce water evaporation when the pool is covered. Easy fit and simple handling: Lightweight, floatable cover is easy to lay on and remove. Can be trimmed to match irregular rectangular pool shapes. Clear size options: Available in multiple widths to suit different pools: 3 ft, 6 ft, 10 ft, 13 ft, 16 ft, 20 ft, 23 ft, and 26 ft. This listing is for the blue 3 x 4 m (10 x 13 ft) rectangular cover. Practical design: Bubble construction provides buoyancy and a close contact with the water surface for consistent coverage. Features and compatibility Intended for rectangular pools of matching or slightly smaller dimensions; measure your pool before to ensure a proper fit. Blue color for standard pool visibility and easy placement. Designed for outdoor pool use and routine pool maintenance practices. Use scenarios Seasonal cover between swim periods: Lay the cover overnight or during short nonuse periods to help keep the pool water cleaner and reduce daily evaporation. Maintenance reduction during windy or leafy seasons: Use the cover when wind or tree debris increases to minimize skimmer and filter cleaning. Offhours heat support: Place the cover in the evening to help reduce heat loss overnight and limit the need for frequent reheating during cooler months. Sizing and care tips Measure the pool surface accurately and choose the nearest larger size if in doubt; excess material can be trimmed to fit. For performance, place the bubble side down onto the water surface so bubbles contact the water. Store the cover clean and dry, folded in a shaded area when not in use. This bubble solar cover provides a practical, lightweight solution for protecting rectangular pools and reducing routine maintenance. Select the correct size to match your pool surface for coverage.
