Description
Anjon Pond Ventilators keep a circular opening in the pond surface during freezing weather so harmful gases can escape and oxygen can enter — critical for overwintering koi and goldfish. The 100-Watt model handles most backyard ponds; the 300-Watt unit is built for larger ponds or harsher climates. Both float on the water and cycle on automatically as temperatures drop.
