Smartpool manufactures a pool blanket in a capsule that dissolves into the pools skimmer. The non-toxic liquid creates a film on the surface that serves as a solar blanket that is unaffected by pool cleaners and is saltwater compatible. 

Solar Direct is a distributor of traditional solar pool covers, liquid pool covers, and winter pool covers.  The solar pool blankets come in many shapes and sizes for both in-ground and above-ground pools. Solar pool covers reduce heating costs and the cost of evaporation. 

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.
