Bubbles Down

One of the more common phone questions that we receive here at Eastgate Pools & Spas this time of year involves solar covers.  Specifically, do the bubbles go up or down?  The answer is down, as the sun heats the air in the bubbles, and this heat is then transferred to the water that comes up between these bubbles.  So, keep those bubbles down and enjoy the warmer water that solar covers provide.
