Play It Koi Tip: To guarantee proper gas exchange under the most extreme winter weather conditions, combine Atlantic's Pond De-Icer and TAKIT0400 Typhoon Aeration Kit. Set the aerator in shallow water below the heater to maximize the efficiency of both products. The rising bubbles going around the Pond De-Icer combine with the heated water to maintain gas exchange under the coldest conditions.
