KobrePond Ice Preventer – Pond Protection Against Ice Formation
The KobrePond Ice Preventer is a pond de-icer designed to maintain an ice-free opening in garden ponds during winter. It prevents the buildup of harmful ice layers that can trap toxic gases and endanger fish and aquatic life.
Styrofoam body with integrated ventilation pipe ensures stable floating position and efficient heat distribution
40 cm diameter provides a large ice-free surface area for gas exchange
24-month manufacturer warranty provides long-term reliability through multiple winter seasons
Low weight of 0.17 kg makes installation and repositioning effortless
What sets the KobrePond Ice Preventer apart
Unlike electric pond heaters, this passive de-icer relies on the insulating properties of Styrofoam combined with a ventilation channel that allows warm water to circulate naturally. The design requires no electricity, no thermostat, and no ongoing operating costs — simply place it on the pond surface and let physics do the work.
Ideal for...
Garden pond owners in temperate climates who need a reliable, maintenance-free solution to prevent complete surface freezing during cold spells. Particularly suited for ponds with fish populations where oxygen exchange through an open water surface is critical for survival.
Application of the KobrePond Ice Preventer
Place the Ice Preventer on the pond surface before the first hard freeze
Ensure the ventilation pipe remains unobstructed and points upward
Position away from pond edges and decorative features for optimal floating stability
Remove and store dry during warmer months for longevity
The KobrePond Ice Preventer is a passive pond de-icer made of Styrofoam with an integrated ventilation pipe. It floats on the pond surface and prevents ice from forming completely by allowing warm water to circulate through the ventilation channel, maintaining an open water area for gas exchange.
The 40 cm diameter is suitable for medium to large garden ponds. The ice-free opening it creates allows sufficient oxygen exchange for ponds housing fish and aquatic plants. For very large ponds, multiple units may be needed for full coverage.
Material: Styrofoam with ventilation pipe. Diameter: 40 cm. Weight: 0.17 kg. Product type: Passive ice preventer (no electricity required). Warranty: 24 months manufacturer warranty.
One KobrePond Ice Preventer unit (Styrofoam body with integrated ventilation pipe, D=40 cm). No additional accessories or mounting hardware required — it is ready to place directly on the pond surface.
No regular maintenance is required. Before winter, place it on the pond surface. After the thawing period, remove it, rinse with clean water, and store dry until the next season. The 24-month warranty covers manufacturing defects during normal use.
