Aeration of a fish or Koi pond is one of the key factors on its well being of the fish within the pond. Without adequate levels of oxygen the fish will become stressed and sit on the surface of the pond to be nearer to the slightly better oxygen levels or try to gulp air from the atmosphere in desperation. When dissolved oxygen (DO) becomes low the pond may not be able to sustain life and oxygen breathing friendly aerobic bacteria which decompose organic matter may not be effective. Fish kill and poor water quality are the usual outcome when this happens. Adding waterfalls or pond spitters will help increase oxygen rich water to the pond but the best long term solution is to add aeration.

Too many plants in a pond can also have a negative effect to pond oxygen levels, During the day plants emit oxygen into the pond buy at night emit carbon dioxide into the pond thus making the situation even more dire if pond as a heavy fish load and atmospheric condition are not in favor of a good pond oxygen level.
