Every living organism requires oxygen, including the bacteria, which are essential to fish health. It is therefore critical that sufficient oxygen levels are maintained within the pond and filtration system.
The absolute minimum concentration of oxygen in a healthy pond is 10 litres of air per 1000 gallons of water. It is most unlikely that a pond can be over oxygenated.
It is important to remember that Air Stones, like many other products, only have a certain life span and will need replacing frequently to maintain optimum performance. |
