Blue Wave 18-ft Round Solar Pool Cover 8‑Mil Blue — Above‑Ground Thermal Bubble Blanket for Heat Retention & Reduced Evaporation

Blue Wave's 18-ft round 8-mil solar pool cover is a lightweight thermal bubble blanket that captures sunlight to raise water temperature, slow heat loss and reduce evaporation for above-ground pools.

This UV-stabilized blue solar cover rests on the water surface and uses thousands of air-filled thermal cells to passively transfer and trap solar heat. Designed for 18-ft round above-ground pools, the 8-mil material balances durability with easy handling so you can place and remove it without heavy equipment. It also blocks falling debris and reduces water loss, helping shorten routine maintenance between swims.

How much warmer will my pool get with this solar cover?

The Blue Wave 8-mil blanket uses passive solar heating to increase water temperature—often by several degrees depending on sunlight, wind and pool exposure. While exact gains vary, many users see notable warming on sunny days and more consistent temperatures overnight.

• Engineered thermal bubbles capture and transfer the sun’s energy into the water.
• Helps maintain warmth overnight by slowing radiative and convective heat loss.
• Works best on sunny, low-wind days and when the cover fits the pool properly.

Will this cover reduce water evaporation and debris?

Yes — the cover forms a barrier over the water that cuts evaporation and limits leaves, dirt and pollen from entering the pool. Fewer contaminants mean less skimming, longer filter runs between deep cleans and lower refill frequency.

• Reduces evaporation—potentially up to significant percentages compared to an uncovered pool.
• Blocks floating debris and reduces chemical loss from top-off water replacement.
• Lightweight surface barrier makes it easier to keep water clearer between uses.

How do I fit, care for, and store the 18-ft round solar blanket?

The cover is sized for an 18-ft round above-ground pool and can be trimmed with scissors for ladder cutouts or obstructions. For best longevity, roll the blanket rather than fold it, keep it dry before long storage, and store in shade away from prolonged direct sunlight.

• Trim with household scissors to accommodate ladders and returns.
• Roll instead of folding to avoid creases; store dry and shaded.
• Remove debris and rinse before long-term storage to prolong polymer life.

How durable is the 8-mil material and what warranty is included?

The 8-mil thickness strikes a balance between easy handling and season-to-season durability when cared for properly. Blue Wave backs this solar blanket with a 3-year limited warranty and leverages over three decades of pool industry experience for product reliability.

• Protected polymer construction resists sun degradation with proper care.
• 8-mil weight offers simple handling for a single person or two.
• 3-year limited manufacturer warranty included for peace of mind.

Who is this for: The Blue Wave 18-ft round 8-mil solar pool cover is ideal for above-ground pool owners who want an affordable, low-effort way to warm water, reduce evaporation and keep debris out between swims. It suits seasonal swimmers, weekend poolkeepers and anyone wanting easier pool maintenance without installing heaters or complex systems. If you need a lightweight, trimmable cover to capture solar heat and extend your swim season, this blanket is a practical choice.
