What separates "pond heaters" from cattle through heaters, live stock tank heaters, and the like are a couple of features:
Laguna Pond Heaters are unique in that they have the indicator light, they float, and they have a separate 15 watt heater on top of the unit to melt snow on contact. This gives the Garden Pond owner assurance that the toxic gasses are escaping the Pond and oxygen can enter so pond fish are not choking to death.
