Review on Sun2Solar Clear 16-Foot Round Solar Cover 1600 Series Heat Retaining Blanket For In-Ground And Above-Ground Round Swimming Pools Use Sun To Heat Pool Water Bubble-Side Facing Down In Pool by Steven Doty

This is like a thick bubble wrap. It is easy to cut to the size of the pool. It floats on top of the water so it doesn’t blow away. Our pool pump was too strong and would push this to the far side of the pool. I used a paper punch to make couple holes and then I tied this to the pool frame above the pump and that kept it in place perfectly. I don’t have a thermometer but It definitely keeps the water warmer. We swam around noon everyday. We had a streak of 100 degree days so one of those days I thought I didn’t need to bother with the cover and then next day the pool was considerably cooler than days we used the cover.
