## Questions & Answers

**Q: which side down**
A: Bubble side down.  The bubbles diffuse the sun's rays into the water warming it better than if the smooth side was down.  Actually it will warm your pool a good 5 to 8 degrees more with the bubbles down (facing the water).  Plus it adheres to the water better in windy situations.  It is also easier to sweep or clean the solar blanket when the smooth side is up.

**Q: Will this help me save water by reducing the evaporation? Or will it heat up the water and cause more to evap?**
A: Even though the water heats up, it's trapped under the cover which minimizes the evaporation rate.  (It would reduce it completely if it was totally sealed) There will be minimal evaporation around the sides, and if there are any holes that allow water to come to the top, but my "refill" rate has been cut at least 75-80%.  Here during the summer, I used to have to refill every 7-10 days. So far I've done it only once in the last few weeks.  Not sure if I can share links, but there is an article on energy (dot) gov on Swimming Pool Covers and it references some good stuff.

**Q: If I don't have a heater for my inground pool will this cover help to warm the water?**
A: Florida: 60 degrees...Utah: 80 degrees.....  Solar covers are much more effective (and necessary) in the dry sunny climate found west of the Rockies than in the more humid climate east of the divide.  In dry climates pools get cold even with lots of sun because almost all pool heat is lost through evaporation, and solar covers effectively reduce that.  In June and July, solar radiation keeps my pool at 80-83 degrees if I cover the pool immediately after swimming to prevent evaporation.

**Q: can I leave the solar cover on the pool for the winter (Florida, no freezing temp)**
A: Sure, you can leave the solar cover on. It will still add some heat into the water but the better use is that it will keep debris out of the pool. Even if the pool is not used during the winter season.
