BigXwell 12-mil Solar Pool Cover 18 ft Round Blue – 1200Series, Thermal Bubble Blanket for Above- and In-Ground Pools

BigXwell's 12 mil, 18-foot round solar pool cover uses thousands of thermal bubbles to capture sunlight, reduce evaporation, and keep above-ground or in-ground pools warmer.

Designed for both above-ground and in-ground pools, this 18-foot BigXwell solar blanket is a lightweight, durable option for homeowners who want to extend swim time, cut water and chemical loss, and shield their pool from debris. The 1200Series cover features a blue color that helps sunlight penetrate while the bubble structure traps heat at the water surface.

How does the BigXwell solar blanket actually raise pool temperature?

The cover's many thermal bubbles collect solar energy during daylight and transfer that warmth into the pool, creating a surface layer that reduces heat loss. It also slows nightly cooling so the pool holds a comfortable temperature longer without active heating.

• 12-mil thickness for improved insulation compared with thinner covers
• Bubble matrix designed to capture and hold solar heat
• Blue tint allows light transmission while reducing glare
• Works passively—no power or connections required

Will this cover cut down on water and chemical evaporation?

Yes—by forming a continuous barrier across the water surface, the BigXwell solar cover significantly reduces evaporation, which means less frequent topping up and lower chemical consumption. It helps stabilize pool chemistry by limiting the loss of treated water.

• Minimizes water loss during hot, windy days
• Reduces chemical depletion from evaporation and UV exposure
• Helps maintain consistent water levels and balance
• Simple removal for water testing and treatment when needed

How well does it protect the pool from debris and dirt?

The cover acts as a physical shield, preventing leaves, dust, and small debris from entering the pool, which lowers cleaning frequency and strain on filters. While not a safety cover, it keeps the surface cleaner between manual or automatic cleanings.

• Covers the water surface to block leaves and airborne debris
• Reduces filter workload and debris accumulation
• Lightweight design makes daily removal and replacement easy
• Suitable for seasonal or daily use depending on pool activity

Is the BigXwell solar blanket durable and easy to handle?

Constructed from quality materials, the 12-mil sheet balances robustness with manageable weight so most users can install or remove it without special tools. It resists typical outdoor wear while remaining flexible for storage when not in use.

• 12 mil thickness for improved longevity versus thinner covers
• Lightweight for one- or two-person handling
• Resilient against normal sun and weather exposure
• Roll-up or fold flat for compact storage

Who is this for: Homeowners with round 18-foot pools who want a cost-effective way to retain heat, reduce water and chemical loss, and keep the pool cleaner between uses. It’s ideal for seasonal pool owners, families that want longer swim seasons without active heating, and anyone seeking an easy-to-use cover for everyday energy savings.
