In The Swim 16 ft x 32 ft Premium Blue Solar Pool Cover - Warms Pool

In this review of the In The Swim 16' x 32' Premium Blue Rectangle Solar Pool Cover, the bottom line is simple: this is a practical, budget-conscious choice for pool owners who want to extend their season by retaining heat and reducing evaporation. It performs exactly as described - a 12 mil thickness that noticeably raises surface water temperature and cuts overnight heat loss - and is best for people who want an easy-to-trim, easy-to-handle cover rather than a heavy-duty insulated blanket. The cover is especially useful when paired with a reel to reduce wear.

Key Features

• 12 mil thickness: The thicker material helps increase surface water temperature by up to 15 degrees so users get more comfortable water without mechanical heating.
• Light blue color: The shade balances heat absorption and retention to warm water while still reflecting enough light to limit overheating on bright days.
• Evaporation control: The cover prevents evaporative heat loss at night, helping maintain temperature and saving water and chemicals.
• Chemistry guidance: The cover should be used only when chlorine is below 2.5 ppm and pH is above 7.2 to avoid material damage and prolong life.
• Reel compatible: Using a solar cover reel makes applying and removing the cover far easier and reduces stress on the material during handling.

Who It's For

This pool cover is aimed at above ground and inground pool owners who want an affordable way to raise and retain pool temperature without installing a heating system. It is suited to people who value easy trimming and handling, and who will pair the cover with a reel for convenience.

It is less appropriate for owners seeking a winter-grade thermal blanket or for those who cannot monitor pool chemistry; the cover requires chlorine below 2.5 ppm and pH above 7.2 to avoid premature wear, so more hands-off users or those needing heavy-duty insulation should look elsewhere.

Pros & Cons

Pros

• Raises surface temperatures noticeably, delivering warmer swims without a heater.
• Good value compared with running a pool heater, with customers citing warmth and thickness as strong positives.
• Easy to trim and install, and compatible with a reel for less handling strain.
• Light blue color offers a solid compromise between absorption and retention.

Cons

• Durability reports are mixed; some users get many seasons while others find life shorter, so longevity can vary by care and conditions.

Frequently Asked Questions

Will this cover raise my pool temperature?
Yes; the 12 mil material is designed to increase surface water temperatures by up to about 15 degrees under favorable conditions.

Can I leave it on overnight?
Yes, the cover prevents evaporative heat loss at night, but follow chemistry guidance and remove or monitor if chlorine climbs above 2.5 ppm or pH drops below 7.2.

Is a reel necessary?
A reel is not required but highly recommended because it makes removal and application easier and reduces wear on the cover.
