Description API AQUARIUM SALT 454GM Electrolytes are essential for the uptake of oxygen and the release of carbon dioxide and ammonia through the gills. A lack of electrolytes may cause serious health problems. API AQUARIUM SALT, made from evaporated sea water, provides these essential electrolytes. AQUARIUM SALT does not evaporate, and is not filtered out, so it should only be added with each water change.
