Water Clarifier for Marine and Freshwater


  • Clears any type of cloudiness
  • Safe for both reef and plants
  • Only clarifier on the market that does it all!

Clarity™ contains both precipitating and flocculating agents in the same bottle, enabling all types of cloudiness to be removed in one dose. Many companies manufacture multiple products to clear up each type of cloudiness and in each different environment. Clarity™ will clear all types of cloudiness in all environments.

Upon adding Clarity™ to the water, you will see a cloudy haze begin to form. This is normal and means that Clarity™ is beginning to work. The water is filled with tiny pieces of floating matter that were not visible to the naked eye. Clarity™ makes those pieces of matter begin to clump together. As they clump together they form larger pieces of matter that are now visible, hence the cloudiness. Once this matter has clumped together, it is a simple matter of mechanical filtration to remove the residue. Matter that was once too small to get caught in filter media is now in large enough clumps.

In order for Clarity™ to work effectively, you should have a filter with mechanical filtration (e.g., filter floss) connected to your aquarium.


Use 1 capful (5 mL) for every 80 L. In some situations the cloudiness may increase after adding Clarity™, however this is normal and is a sign that Clarity™ is actively working. Rapid clarification will follow (1–2 hours). In the case of chemical or particulate clouding clean filter floss or cartridge after tank clears.
