Clarity is the ultimate clarifier for both fresh and saltwater. It employs an advanced polymeric flocculating agent that is both reef and plant safe. Seachem - Clarity will clear all types of clouding including, but not limited to, chemical clouding and particulate clouding (i.e. stirred up gravel bed).
Upon adding Seachem - Clarity to the water, you will see a cloudy haze begin to form. This is normal and means that the flocculating agent 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 peices 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.
Use 1 capful (5 mL) for every 80 L (20 gallons*). In some situations the cloudiness may increase slightly after adding Seachem - Clarity, however this is normal and is a sign that it is actively working. Rapid clarification will follow. In the case of chemical or particulate clouding clean filter filter floss or cartridge after tanks clears.
