Blue Wave 12x20 ft Solar Pool Cover — 12-mil Blue Thermal Bubble Blanket for Heat Retention & Reduced Evaporation

If you want more comfortable swim temperatures without running a heater, this blue 12-mil solar cover is engineered to sit on the water and use thousands of air-filled bubbles to transfer and store solar energy. It’s sized for a 12 x 20-foot rectangle pool, trims easily for ladders, and fits both above-ground and inground setups. Lightweight yet durable, the cover simplifies seasonal use and helps keep debris out between swims.

How does this solar cover warm my pool and keep heat overnight?

The cover’s downward-facing thermal bubbles collect solar energy during daylight and pass that warmth into the water, while the material forms a light insulating barrier at night to reduce heat loss. It doesn’t replace a heater but raises daytime temperatures and slows overnight cooling for longer comfortable swim windows.

• Thousands of air-filled bubbles transfer and trap heat efficiently.
• Blue surface color aids heat absorption and nighttime retention.
• Reduces temperature drop overnight compared with an uncovered pool.

Will this cover fit my pool and how do I handle installation?

This blanket ships sized for 12 x 20-foot rectangle pools and is compatible with both above-ground and inground pools. Installation is simple: lay it floating on the water surface, trim with household scissors around ladders or fittings, and remove or roll it when not in use.

• Trim-to-fit design for ladders and skimmers—no special tools required.
• Lightweight 12-mil construction makes placement and removal easier.
• Suitable for seasonal use from spring opening through fall closing.

How does the cover reduce maintenance and water loss?

Beyond heating, the solar blanket forms a surface barrier that limits evaporation and blocks leaves, pollen, and other debris. That means less frequent topping off and skimming, saving water and reducing pool chemical adjustments between uses.

• Significantly lowers water evaporation compared to an uncovered pool.
• Keeps out common debris, cutting down on cleaning time.
• Helps maintain more stable chemical levels by reducing dilution.

What care and storage practices extend the cover’s life?

Proper handling extends performance: roll instead of fold, keep it shaded when stored, and ensure the material is dry before long-term storage. Regularly removing debris and avoiding sharp objects will preserve the 12-mil film and bubbles.

• Roll the cover for storage to prevent creases and weak points.
• Store in shade and sheltered from UV when not in use for long periods.
• Inspect for tears and trim carefully around hardware to prevent damage.

Who is this for: The Blue Wave 12x20-ft 12-mil rectangle solar pool cover is ideal for pool owners who want a cost-effective way to raise water temperatures, cut evaporation, and keep debris out without installing mechanical heating. It suits families with above-ground or inground pools who value easy handling, seasonal performance, and a product backed by decades of pool industry experience and a 5-year limited warranty.
