Seachem Pond Salt 20kg

Pond Salt is a chemically sound blend of salts designed to replicate the native ionic environment of goldfish and koi without adversely impacting on pond plants when used at the recommended dosage. It can also be useful to temporarily reduce nitrite toxicity in an emergency situation. It does not impact pH. Directions: When setting up a pond and when making water changes: 100g (5 tablespoons) for each 200L (50 US gallons). This amount will yield 0.5 ppt. Once every 6 months: 250g (12.5 tablespoons) for each 200L (50 US gallons). For emergency relief of nitrite toxicity: 1kg (3 US cups) for each 200L (50 US gallons).
