Ventilation stone ball 2.5 cm

Oxygen as a product of photosynthesis and as a substrate for cellular respiration is essential for the functioning of any ecosystem, including ponds. In practice, the gas exchange between air and the water surface is too low to prevent hypoxia (asphyxiation), which is dangerous for aquatic organisms. Therefore, additional aeration of the water is required to maintain the biological balance in the tank. The Happet ventilation stone will help with this. Connected to a pump or aerator, it ensures good water circulation and oxygen supply. During the summer heat, it balances the release of oxygen into the atmosphere through the pond. In winter, it enables the hibernating fish to survive by preventing the water surface from freezing. Thanks to its stable construction, the Happet aeration stone can be placed on the pond floor without any additional weight.
