Kasco Dock Deicer | Select model from 1/2 hp to 1 hp 

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 de-icers push warm bottom water to the surface preventing and eliminating ice formation. Our deicers can create an ice-free area as large as 90 ft. in diameter, helping to ensure your fish and property will be protecting 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 deicers fit a variety of applications as they can be anchored with ropes or use a dock mount. 

Deicers push warm bottom water to the surface creating an ice-free area of protection around your boat, dock, pier, or other in-water property. They help protect fish and aquatic species, by allowing for open areas where oxygen can enter the water. Kasco de-icers come with (2) 20 ft. suspension ropes and are available in 1/2, 3/4, and 1 HP unit sizes. Use deicers year-round for improved health and beauty of your water
