Understanding PPM in Water Chemistry
PPM stands for parts per million, which is a unit of measurement used to express the concentration of a substance in water. In the context of koi ponds, PPM is used to measure the amount of salt in the water.
When it comes to water chemistry, PPM is an important metric to understand because it helps determine the suitability of water for different purposes. For example, drinking water should have a low PPM to ensure that it is safe for consumption, while koi ponds require a specific PPM range to maintain the health of the fish.
PPM is measured using a TDS (total dissolved solids) meter, which measures the number of particles in the water that are too small to be seen with the naked eye. The higher the PPM, the more particles there are in the water.


In koi ponds, the ideal PPM range for salt is between 1000-3000 PPM, or 0.1%-0.3%. This range helps prevent over-saturation, which can harm the koi and other aquatic life. It also helps maintain the proper salinity levels in the pond to prevent stress and disease among the koi.
To maintain the proper PPM range in a koi pond, regular monitoring is necessary. This can be done using a TDS meter or a test kit. If the PPM is too low, salt can be added to the water. If the PPM is too high, water changes may be necessary to dilute the salt concentration.
Overall, understanding PPM in water chemistry is crucial for maintaining the health and well-being of koi fish in a pond. By monitoring and maintaining the proper PPM range, koi pond owners can ensure that their fish are healthy and disease-free.
