The new solar sun ring with palm tree design is a passive solar swimming pool heat retention device made from two sheets of heavyweight U.V resistant vinyl. At night the contained air acts as an insulating blanket to retain heat gained during daylight. Solar sun rings are equipped with six magnets to improve clarity and decrease hardness of the water in your pool. The magnets are positioned to facilitate rafting. The strength of the magnets will permit single position removal but will easily separate to prevent entrapment in accidental falls.
