Try Koi Toolkit PRO →Salt is a powerful and versatile tool in the koi hobby, but accuracy is paramount. Using an accurate koi pond salt calculator ensures you achieve the correct therapeutic percentage without overstressing your fish. We recommend using only high-quality PDV salt for ponds (Pure Dried Vacuum) to ensure no anti-caking agents are introduced to your system.
Common salinity targets include 0.3% for a general health tonic and reducing osmotic stress during new fish arrivals, or 0.6% for treating specific parasites like Trichodina or Costia. Our salinity calculator converts these percentages into exact kilograms or pounds based on your specific pond volume.
Before salting your pond, ensure you have removed any Zeolite media from your filters, as salt causes Zeolite to dump all its absorbed ammonia back into the water instantly. Additionally, many aquatic plants will not survive salinity levels above 0.3%. Always increase salt levels gradually over several days to allow your koi's kidneys to adjust.
