In The Swim 28ft Premium Blue Round Solar Pool Cover - Heats & Retains

In this review the In The Swim 28' Premium Blue Round Solar Pool Cover is assessed for pool owners who want a low-cost, effective way to raise and maintain water temperature. The bottom line: this 12 Mil polyethylene cover is best for people who want noticeable heat gains and reduced evaporation without complicated installation. The cover's thickness and light blue color combine to retain heat overnight and increase daytime water temperature, making it a practical pick for above ground and inground round pools when basic chemical conditions are met.

Key Features

• 12 Mil thickness: Provides stronger heat retention and durability compared with thinner covers, helping water temperature climb by several degrees during sunny periods.
• Light blue color: Balances heat absorption and retention so the cover warms water effectively while limiting excessive heat loss at night.
• Evaporation prevention: Reduces evaporative heat loss overnight, which helps maintain pool chemistry and conserves water.
• Simple material: Made from lightweight polyethylene so the cover is easy to handle and trim to fit irregular shapes.
• Reel compatibility: Works well with a solar cover reel to make removal and application easier and reduce wear on the cover.

Who It's For

The cover is ideal for owners of round above ground or inground pools who want an affordable way to extend their swim season and reduce heating costs; it suits people who prefer a simple, no-fuss solution that can be trimmed to fit. It also works well for those who will use a cover reel to improve convenience and longevity.

Customers who need exact, tailored shapes or who run pools with unusually high chlorine or low pH should look elsewhere or take care: the cover should only be used when chlorine is below 2.5 ppm and pH is above 7.2. For very high-end solar performance consider thicker specialty films not represented here.

Pros & Cons

Pros

• Durable 12 Mil construction delivers reliable heat retention and can raise water temperature noticeably in sunlight.
