Water Quality for Koi Health
                                                                                                                                     

Is your pond providing ideal living conditions for its inhabitants?   Proper water quality is the foundation for success in your Koi pond.   Sometimes, despite our best efforts, it is not uncommon to encounter issues that end up compromising  Koi pond water quality.  For the Koi hobbyist, the challenges to restore water quality remain the same.  What needs to be done to initiate or restore good water quality to your pond?

To keep fish healthy, your Koi pond water needs to stay within certain parameters.   These include not only moderate temperatures, but also sufficient oxygen, a relatively neutral pH, the absence of chlorine compounds, and minimal amounts of nitrites and ammonia.  The pH is a measure of the pond water's acidity/alkalinity.  A good pH level for your pond is 7 which is neutral.  Nitrates and ammonia come from both fish waste and fertilizer runoff.

Because good  water quality parameters are so important for Koi, you will need a thermometer, a kit for testing pH, a kit for testing ammonia and/or nitrites, a dechlorinating formula if your water supply contains chloramine, or chlorine dioxide, pond salt, a parasite treatment or preventive, an aeration kit, one or more plastic buckets for transporting fish, a soft net for guiding fish into the bucket, and an aquarium or holding tank for sick or new Koi.   

  •      A thermometer.  This is crucial for knowing when to begin feeding your fish in the Spring and when to stop feeding them in the fall.   Also, as temperatures rise in the Spring, their diet can be changed from wheat germ to protein once the water temperature is above 70 degrees.
  •        A kit for testing pH.  As mentioned earlier, Koi fish need a pH level near neutral somewhere between 6.5 and 7.5, is perfect for good koi pond water quality.  You should regularly test your Koi pond water to see whether it falls within this range, especially after adding new fish or plants or after a more than 20 percent water change.
  •       A kit for testing ammonia and/or nitrites.  Ammonia and/or nitrites can build up from fish waste when a pond is overpopulated.  If your test kit does not test for these levels you will need to purchase a separate testing kit, as water quality will be greatly affected in the presence of these harmful conditions.
