Atlantic Pond De-Icer - 300 Watts
Energy-Efficient Winter Pond Protection
Atlantic's Pond De-Icer maintains a small area free of ice, allowing oxygen in and toxic gases like carbon dioxide and methane out of pond water during winter. Engineered with an intelligent thermostat that cycles on and off automatically, this energy-efficient de-icer saves power while protecting your fish through the coldest months. Constructed from high-strength, high-temperature PPS polymer, it delivers maximum durability and reliable performance season after season.
Intelligent Thermostat Technology
Unlike basic heaters that run continuously, Atlantic's Pond De-Icer features an internal thermostat that turns the heating element on just above freezing and off as water warms. This automatic cycling saves energy while maintaining a critical ice-free zone for gas exchange. The efficient 300-watt heating element only draws power when needed, keeping operating costs low while ensuring your pond remains properly ventilated throughout winter.
Visual Operation Indicators
The built-in indicator light provides at-a-glance status monitoring. A blue light shows the de-icer is in standby mode when plugged in with water temperature above freezing. When the light turns green, it indicates water temperature has dropped below freezing and the de-icer is actively heating. This visual feedback ensures you always know your de-icer is working properly.

Applications
Ideal for koi ponds, goldfish ponds, water gardens, and any pond with fish that requires winter gas exchange. Essential for preventing winter fish kills caused by toxic gas buildup under ice. Perfect for moderate climates and ponds where a small ice-free area is sufficient for proper ventilation.
Why Winter De-Icing Matters
When a pond freezes over completely, oxygen cannot enter the water and toxic gases like carbon dioxide and methane cannot escape. Fish and beneficial bacteria continue to consume oxygen and produce waste gases throughout winter. Without gas exchange, oxygen levels plummet and toxic gases accumulate, leading to fish stress, illness, or death. A pond de-icer maintains a critical opening in the ice, ensuring continuous gas exchange that keeps your fish healthy until spring.
Frequently Asked Questions
Q: How large of an area does the de-icer keep ice-free?
A: The de-icer maintains a small area free of ice, typically several feet in diameter depending on air temperature and wind conditions. This is sufficient for gas exchange in most pond applications.
Q: Will the de-icer heat my entire pond?
A: No, the de-icer is designed to maintain a small ice-free opening for gas exchange, not to heat the entire pond. This targeted approach is energy-efficient and sufficient for fish health.
Q: How much does it cost to run the de-icer?
A: At 300 watts, the de-icer is very economical. Since it cycles on and off based on temperature, actual runtime varies. In moderate climates, operating costs are typically just a few dollars per month.
Q: Can I leave the de-icer running all winter?
A: Yes, the de-icer is designed for continuous winter operation. The automatic thermostat ensures it only heats when needed, making it safe and efficient to leave plugged in throughout the cold season.
Q: Where should I place the de-icer in my pond?
A: Float the de-icer near the surface in a location away from where fish typically gather. Avoid placing it directly over deep areas where fish may winter. The 20-foot cord provides placement flexibility.
Q: What do the indicator lights mean?
A: Blue light indicates standby mode (water above freezing, heater off). Green light indicates active heating (water below freezing, heater on). This lets you verify operation at a glance.
Q: Is the de-icer safe for fish?
A: Yes, when used as directed, the de-icer is safe for fish. The heating element is enclosed in durable PPS polymer, and the unit maintains safe water temperatures while preventing ice-over.
Q: Can I use the de-icer in extremely cold climates?
A: The de-icer maintains an internal temperature of 200°F under worst conditions and is suitable for most climates. In extreme cold (sustained temperatures well below 0°F), you may need additional de-icers or higher-wattage units.
Q: Do I need to run my pond pump in winter?
A: This depends on your climate and setup. In moderate climates, a de-icer alone may be sufficient. In colder areas, running a pump can help maintain the ice-free area. Consult winter pond care guidelines for your region.
Q: What is covered under the 1-year warranty?
A: The 1-year warranty covers manufacturing defects and material failures under normal use. Consult your warranty documentation for complete terms and conditions.
