  Make a strong brine solution by dissolving noniodized table salt in warm water at a rate of at least 4 tbsp. to 1 cup of warm water. More can be used, but it will not enhance the effect to any appreciable degree.
  
  
• 2). Immerse the zeolite in the brine, and let it soak for at least nine hours. A 24-hour soak is best.
  
  
• 3). Rinse the zeolite thoroughly with fresh water. Tap water will work just fine, but distilled or reverse osmosis water can be used for a final rinse if you have concerns about contaminants.
  
  
• 4). Replace the zeolite in the aquarium filter.
  
  

Heat Method

• 1). Preheat an oven to 350 degrees Fahrenheit.
  
  
• 2). Remove the zeolite from its mesh bag or other container and spread the zeolite in a single layer on a baking sheet.
  
  
• 3). Place the zeolite in the oven and let it bake for 30 minutes.
  
  
• 4). Remove the baking sheet from the oven and allow the zeolite to cool before placing it back in its filtration container.
  
  

Sun and Air Method

• 1). Place the zeolite on a baking sheet or other flat, portable surface and spread it out in a single layer if possible. If it is enclosed in a sealed mesh, simply place the bag on the surface.
  
  
• 2). Put the zeolite in a location where it will receive direct sunlight for the greater part of the day.
  
  
• 3). Allow the zeolite to sit in the sun and fresh air for two days.
  
  
• 4). Rinse the zeolite and place it back into its filtration container.
