Pond Prime is a complete conditioner that removes chlorine, chloramine, and detoxifies both ammonia and nitrite. It also provides essential ions and stimulates natural slime coat. Pond Prime also enhances nitrate removal. It should be the first choice conditioner when setting up a pond, adding, or changing water. No other product is required to make water safe. Unlike competing products, Pond Prime does not cause a pH drop.
 
It is very concentrated: 250 mL (1 cup) treats 20,000 L (5,000 US gallons).
