Koi Pond Aeration » Ceramic Air Stones » Japanese Ceramic Air Stones

Many Koi keepers, unfortunately are not aware of the importance of air in both the pond and more importantly within the actual biological side of the filtration system, please remember that every living thing, including bacteria survive only with a source of air and the benefits of air within the filtration system will be seen in a very short space of time.
 
Air Stones like many other products, only have a certain life-span and do need replacing frequently to maintain optimum performance.
