The Solar Sun Ring is a solar swimming pool heating device made from two sheets of U.V. resistant vinyl. The top clear layer holds insulating air and focuses sunlight on the blue colored bottom layer. Solar Sun Rings may be used on chlorine or salt water system pools, and both in ground or above ground.  The spacing between the rings lets sunlight through, which reduces the incidence of mustard algae.

Doheny's manufactures solar blankets in three variations- blue, Clear-Tek blue, and Clear-Tek clear.  The clear blanket is proven as the best blanket for raising and maintaining the temperature, as the most sun is allowed to come through.  Water temperature is raised as much as 15 degrees by the Clear-Tek clear blanket.
