Keep your fish safe and happy in icy winters with the Cobalt Anti-Ice Pond Heater. Its floating style keeps heat at the surface, while the 100-watt ceramic heating element ensures low energy consumption. It's durable, too—shock- and UV-resistant. For ponds with a surface area up to 54 sq.ft (for larger ponds, more than one unit is required). Made in Italy. Three-year warranty.
