## Questions & Answers

**Q: How much warmer will my water get?**
A: Our solar covers will raise water temperature up to 15 degrees fahrenheit!

**Q: Does the cover’s color matter?**
A: Blue solar covers are effective in trapping heat and conserving chemicals. When pool water is properly balanced their color resists fading.

**Q: How does my solar cover heat my pool?**
A: Solar covers are made of thermal bubbles that capture the sun's UV rays to create and retain heat naturally. It is important to the bubble side down into the water to work effectively.

**Q: How do I trim my solar cover to size if I have extra material?**
A: Our solar covers allow for trimming to ensure a perfect fit whether your pool is round, oval, rectangular or even a unique shape!

**Q: Do your covers work with solar reel systems?**
A: Our solar covers will fit most solar reels. While a reel isn’t required for a solar cover, it makes removal and positioning easier.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great value, works amazing!!
*by V***Y on August 20, 2025*

We love our solar blanket. Our pool water has never been this warm. Great value, heavy duty and works great. Would highly recommend.

### ⭐⭐⭐⭐⭐ Good product for price point.
*by D***S on June 17, 2025*

Heavier duty than expected.

### ⭐ Inferior product. Not durable to withstand heat from sun.
*by L***E on June 10, 2025*

Surprised when package arrived on door step, very thin solar cover. I opened the top to confirm that it wasn't close to my current 800series solar cover which is 3 years old. Extreme heat from the sun has broke down they strength of the cover over using it three seasons, the new cover that arrived Monday isn't going to holdup in this area for one season.
