Aquascape Pond Salt provides a wide variety of benefits for ponds and pond fish, acting as a treatment and preventative measure. Our pond salt helps to reduce the effects of elevated nitrite levels that become toxic to pond fish. It also helps restore natural electrolytes, allowing proper gill function when pond fish are under stress. This non-iodized salt also repairs and promotes a natural slime coat, effectively helping to prevent disease. Each scoop will treat 190 gallons of water and the entire container treats 1,520 gallons total.
