Ammonia level nitrite level nitrate level and pH. Most fish prefer a pH value of 72 to 76 or just slightly on the alkaline side of the scale. If the DO content of surface water is measured equal to 82 mgl in a freshwater pond located at 300 m altitude and if the water temperature is 30C you find from the chart Variation of oxygen saturation with altitude that the 100-percent saturation value is 727 mgl.

Partial water changes are the norm and are key to maintaining the koi pond environment. As a minimum you should monitor the amounts of ammonia and nitrites in your system. A 10-20 weekly water change is much less stressful to your koi than an abrupt 50 monthly change.
