Contains Naturally Occurring Marine
    Biopolymers
  
  
    Tropic Marin Bio-Actif Salt mix has been professionally
    designed to be used in reef tanks that employ some type of
    carbon dosing to create an Ultra-Low Nutrient System (UNLS).
    The unique salt incorporates bio-active marine agents that
    help protect and enhance your aquarium's fauna growth, leading
    to more vibrant and healthier corals. Healthy corals will
    naturally grow faster and are more robust, but Bio-Actif salt
    is great for fish too by increasing the protection
    against damage to mucous membranes, heightened
    sensitivity, and elevated mating activity.

    Instructions:
  
  
    We suggest starting with 1/2 Cups of Tropic Marin
    Bio-Actif Salt per 1 Gallon of RODI water. For the best
    results, the water should be circulating and at a temperature
    of 73-77 °F. Once the water is up to temperature and
    circulating, slowly adding the appropriate amount of salt will
    allow it to fully dissolve quickly without creating any
    concentrated areas where precipitation may occur. The freshly
    mixed solution may be slightly cloudy but will clear once it is
    added to the tank.
  
  
     
  
  
    Important - Using conductivity with
    freshly mixed Bio-Actif saltwater will show about 10% low. It
    is recommended to use specific gravity for reading Tropic Marin
    Bio-Actif Salt. 
  
  
     
  
  
    When you have added almost all of the salt and the mixture is
    fully dissolved, start measuring the specific gravity with a
    refractometer or similar instrument. Keep adding small amounts
    of salt until the specific gravity is the value you desire. The
    specific gravity of the sea salt solution should range from
    1.025 to 1.027 (at 73-77 °F / 23-25 °C) and the pH -value
    should be in the range of 8.0 – 8.4. If all parameters are
    correct, the salt water is ready to use.
