Clarity is the ultimate clarifier for both fresh and saltwater. It employs an advanced polymeric flocculating agent that is both reef and plant safe. Clarity is the only clarifier on the market that does it all! Clarity will clear all types of clouding. Many companies manufacture multiple products to clear up each type of cloudiness and each different environment (e.g. freshwater, marine, reef, etc.). Some companies have developed products that will clear most types of cloudiness, but their application requires two separate bottles of product. Clarity contains compounds that will clear all types of cloudiness in all environments. Clarity contains both precipitating and flocculating agents in the same bottle, enabling all types of cloudiness to be removed in one dose. Upon adding Clarity to the water, you will see a cloudy haze begin to form. The water is filled with tiny pieces of floating matter that were not visible to the naked eye.
