PondCare’s all-natural sea salt replaces electrolytes including potassium, sodium, calcium and magnesium. These are essential for koi’s uptake of oxygen as well as the release of carbon dioxide and ammonia. Helps reduce toxic effects of nitrite.
Desired salinity levels will vary by pond owner & application. Here are some examples of how to raise salinity.
500 gallons to 0.1% (1 ppt) = add 4.1 pounds of salt
500 gallons to 0.2% (2 ppt) = add 8.3 pounds of salt.
50 lb. quantities are available -please contact me for prices.
