Koi Pond Aeration

All Ponds need a plentiful supply of oxygen especially a koi pond. Both your fish and the biological filter will require large amounts of oxygen to thrive.

Always purchase a good quality air pump such that can power several air stones even at five or six feet depth. It is a good idea to place a few air stones directly in the filter system to provide oxygen for the filter bacteria as well as in the pond itself.

Oxygen can also be added by water splashing into the pond on its' return from the filter and waterfalls are especially effective in this respect. However, bear in mind if building a large waterfall the possible nuisance from the noise at night and also put in a system to bypass it in the winter. A large waterfall will have a big cooling effect on the water.

There is a lot less worry about the oxygen levels in the winter as cold water holds far more oxygen than warm water and your fish will be less active and require less oxygen.
