Complete Aquatics Pond Salt - 10 lbs Pond salt has been termed “The Koi Wonder Drug” and is a proven staple in the health care and maintenance of Koi and other pond fish. Pond salt maintained at a 0.2% level will reduce fish stress, enhance their slime coat and improve gill function. During periods of stress and disease, healthy gill function (osmoregulation) is compromised, causing a loss of electrolytes which can lead to serious healthproblems for fish. Complete Aquatics Pond Salt reduces stress and provides the essential electrolytes fish need to survive. In addition, a pond salt solution will do a great job at controlling certain protozoan parasites, such as Trichodina, Ich and Chilodonella. Salt does not evaporate or get filtered out, so the only time you will need to add more salt is when you do water changes. A greater than 0.3% salt level may harm some more tender aquatic plants. • All-natural, contains no added chemicals that could harm fish• Improves gill function• Protects against nitrite toxicity• Reduces fish stress• Helps maintain a stout slime coat on the fish and a natural balance of electrolytes• Safe to be used with other treatments & bio-filter
