New recommendations highlight best pond de-icers to protect fish from winterkill

Pond de-icers are essential for preventing "winterkill" in fish by keeping ponds from freezing completely. New recommendations highlight the importance of factors like pond size, durability, and type of de-icer, with options ranging from submerged to floating models. The best de-icer, Kasco’s Marine Lake and Pond De-icer, is stainless steel and suitable for larger ponds. TetraPond’s De-icer is a budget-friendly choice for smaller ponds, while Farm Innovators’ Pond De-Icer is durable for tanks up to 600 gallons. Prices for de-icers start at $40 for basic models, with mid-range options costing between $50 and $100. Professional-grade models can exceed $600. Consider cord length and energy efficiency when selecting a de-icer.
