Rocks 'n' Roots Blog - Aeration
Q. Do I really need aeration for my pond? Isn't it only helpful to ponds with a lot of fish in them?
A. For years aeration was thought of as something you only needed if you had high fish loads in a pond. Through years of working closely with pond owners it has been proven that aeration does far more than just keep fish alive. In fact, we consider aeration to be the single most important step in maintaining a healthy pond. Without oxygen nothing will decompose. All the fish waste, dead algae/plant material, leaves, etc. that fall to the pond bottom will only continue to build up unless there is good oxygen levels to help it decompose. A bottom mounted air diffuser can make a huge difference in a ponds health by bringing oxygen and circulation down where its needed the most - along the pond's bottom.
