Super concentrated formula 

For best results, add H2O Neutralizer to tap water before adding water to your pond. Use 1 tsp (5 ml) per 50 U.S. gallons (189 L).

Each cup treats 2,400 gallons. 

If treating pond for ammonia, nitrite or nitrate, base dose on pond volume. 

For extremely high levels of chloramine or nitrite, dosage can be repeated or increased up to 5x within a 24-hour period. DO NOT OVERDOSE. 

A sulfur odor is normal and dissipates rapidly after use. In certain rare conditions and in low oxygen environments, this product may reduce dissolved oxygen levels. Ensure there is adequate circulation/aeration before adding. 

This product will affect the accuracy of Nessler-type ammonia test kits and Winkler-type oxygen test kits. Salicylate ammonia test kits are recommended.
