Global Warming? Not in our backyard...

In an attempt to heat the pool water (we are all anxious to begin the swimming season) we purchased Solar Sun Rings. According to the literature: Total heat input of 21,000 BTU per day, per unit. Inflatable rings 60" in diameter with 6 magnets each for easy attachment of rings. Coverage should equal 70-80% of your pool surface. (We think we need to buy at least one more ring) Time will tell if the water temperature rises (we'll let you know, AlGore). Last Summer, the pool was never a "comfortable" water temp - though the kids and Jewels did just fine, I don't like to be chilled.
