This Sinking De-icer will sink to the bottom of the pond, and is thermostatically controlled with an automatic shut-off. Since it operates at the bottom of the tank, it is less likely to be disturbed by fish.
Each unit comes with a galvanized wire Guard/Stand With the guard in place, the Sinking De-icer may be used in plastic ponds.
Spare Me! Keep a spare air pump or water pump on hand for emergencies. If your pump ever stops, do not feed your Koi.
Consider using seperate water pumps for your waterfall and filter. This way you will always have a backup, and you can save energy.
