Oase IceFree 4 Seasons (72931)
Every winter, the same problem occurs: The pond freezes up completely and toxic gases build up at the bottom of the pond that cannot escape. Toxic gases create a lack of oxygen in the water and cause the poisoning of living organisms. Due to this lack of oxygen, fish and microorganisms have practically no chance of survival.
The Oase IceFree 4 Seasons is the solution to this problem. The Oase IceFree 4 Seasons aerates the water and allows harmful fermentation gases to escape by continuous movement of water. It keeps an area of the pond free of ice in temperatures down to -4°F and maintains the warm temperature zones on the pond floor. The Oase IceFree 4 Seasons is powered by an energy-efficient pump without the use of an additional heating element. During winter months the IceFree creates a small hole to allow the important exchange of gasses at the surface of the water, which allows your fish to breathe easily. The IceFree 4 Seasons comes with 2 nozzle heads so you can utilize it as a small fountain in your pond during the rest of the year.
