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.
You should stop feeding your aquatic plants about a month before the first frost in your area. Even in areas that don't normally have frost, plant growth slows in the shorter, cooler days of the fall and winter months.
