How It Works

Water conditioners neutralize chlorine and chloramine, which are lethal to fish even in small amounts. Dose for the volume of water being added, not the entire tank volume. Products like Seachem Prime also temporarily detoxify ammonia and nitrite for 24-48 hours, making them useful during emergencies.
