  •  Outstanding customer service

The Kasco Deicer is your best defense against winter fish kills and damage to property due to ice formation and expansion. By providing superior thrust and water movement, Kasco's deicers push warm bottom water to the surface preventing and eliminating ice formation. Our marine deicers can create an ice-free area as large as 90 ft. in diameter, helping to ensure your fish and property will be protected throughout the winter. Kasco's deicers can also be used in warmer climates to help promote proper circulation of water to improve overall water quality. By providing circulation, you'll be eliminating foul odors and stagnant water areas, may help limit floating plant growth, and eliminate floating debris. Kasco marine deicers fit a variety of applications as they can be anchored with ropes or use a dock mount.
