Aeration stone ball 2,5 cm

Oxygen as a product of photosynthesis and a substrate for cellular respiration is essential for the functioning of every ecosystem, including ponds. The gas exchange between air and water surface is in practice too small to prevent hypoxia (asphyxia) dangerous for aquatic organisms. Therefore, additional aeration of the water is necessary to maintain the biological balance in the tank. The Happet aeration stone will help with this. Connected to a pump or an aerator, it allows for proper water circulation and oxygenation. During the summer heat it balances the oxygen release to the atmosphere through the pond. In winter it enables the survival of wintering fish by preventing the water surface from freezing. Thanks to its stable construction, the Happet aeration stone can be placed at the bottom of the pond without any additional weight.
