The Alita AL-40 is the perfect aeration pump for ponds bewtween 2,000 & 4,000 gallons. Can be used for winter aeration when the water fall is shut down or provide aeration to the pond all year long. Fish and other pond life need oxygen to live and remain healthy. Filter bacteria also require oxygen to break down toxic fish waste. Aeration of the pond is particularly important in warm weather when the water holds much less oxygen, and also at night when oxygenating plants stop producing oxygen and start using it. Using an aeration pump system increases water circulation & prevents stagnation. It increases oxygen levels in the pond or filter chamber thus improving fish health and filter efficiency.
