This De-icer is designed to float in the water and is thermostatically controlled with an automatic shut-off. The styrofoam float is completely enclosed within a rugged plastic housing. The cord exits from the top of the unit - cord length is 15'
If your pond is made of rubber or plastic you should purchase the optional guard.
This guard (shown top-right not to scale) easily snaps onto several plastic API models of de-icers. It is constructed of galvanized wire and assembled without the use of welding, forming a much more sturdy and durable guard.
Most pondkeepers know that the best way to ensure clear pond water is with an ultraviolet sterilizer. Some often overlooked factors are what to do when the UV light is not doing the job anymore. Usually, this is a simple as an old lamp. Depending on the brand, UV lamps should generally be replaced about every 12-15 months of use.
