Finest-Filters Floating Pond Heater for Koi Fish Pond Anti Ice Winter 150/300 / 600w (600w)

• These pond heaters are a perfect way to protect your fish over the winter. Designed to stop the pond surface from freezing over in one localised area, allowing essential gas exchange. This protects fish and aquatic life during winter.
• This device is not intended to heat the entire pond. It maintains an opening in the ice so oxygen can enter and harmful gases (CO₂, methane, ammonia) can escape.
• Automatically switches on when temperatures drop near freezing and off again as conditions warm. Energy-efficient and safe for continuous winter use.
• These heaters come complete with a floating ring, allowing the heater to float, and a 5 meter cable, with 3 pin UK plug.
• The 150w model is ideal for ponds up to 10,000 litres, the 300w model up to 20,000 litres, and the 600w up to 40,000 litres.
