KETNET Solar Bubble Pool Cover 8 ft Round — 12-mil Thermal Blanket, UV-Resistant, Reduces Evaporation

If you want a simple, low-effort way to keep pool water warmer, save water, and cut cleaning time, this 8-foot KETNET solar bubble cover is designed to do just that. Made from thousands of small air cells, the cover captures sunlight and forms an insulating layer on the water surface. It’s waterproof, UV-resistant, and thicker than many competitors at 12 mil for stronger tear and tensile resistance.

How does this cover actually warm my pool water?

The bubble pattern acts like miniature solar panels—each air pocket traps heat from sunlight and slows heat loss overnight. The result is a measurable increase in surface temperature without running additional heaters.

• Thermal bubbles concentrate solar energy directly at the water surface.
• 12 mil thickness holds heat longer than thinner covers.
• Floating design maximizes sun exposure across the pool area.

Can it reduce water loss and keep the pool clean?

Yes. By covering the water, the blanket dramatically cuts evaporation and blocks airborne debris like leaves and dust. That translates to less refilling and fewer filter runs or manual cleanings.

• Reduces evaporation by up to 95% when properly fitted.
• Prevents leaves and dirt from entering the water surface.
• Helps extend time between chemical rebalancing and skimming.

Will the cover fit my pool and how do I handle different shapes?

This model is sized for an 8 ft round pool but can be trimmed to match nonstandard shapes. Use a marker and sharp scissors to cut custom curves or straight edges; the material is formulated to remain effective after trimming.

• Standard compatibility: 8-foot circular pools (above ground or inground).
• Easy to cut to fit irregular shapes—round, oval, or rectangle.
• Waterproof and UV-stable so cut edges stay durable in sun and water.

How durable is the KETNET solar blanket and what maintenance does it need?

The cover is manufactured at a heavier 12 mil thickness for increased tear and tensile resistance versus many common 4–10 mil options. Minimal maintenance is required: rinse occasionally and store away from sharp objects when not in use.

• 12 mil vinyl resists fading, warping, and small rips in normal use.
• Rinse with fresh water to remove chemicals or debris; avoid abrasive surfaces.
• Store folded or rolled in shade to extend service life between seasons.

Who this is for: KETNET’s 8 ft Solar Bubble Pool Cover suits homeowners with small round above-ground or inground pools, spa owners seeking a low-cost heat-retention solution, and anyone wanting to conserve water and reduce pool-cleaning chores. If you want a thicker, easy-to-trim solar blanket that balances durability with straightforward operation, this model is a practical, budget-friendly option.
