1. Seachem Clarity 500ml

By Seachem Store

Seachem Clarity 500ml

CLARIFIER: Clarity is the ultimate clarifier for both fresh and saltwater tanks. Clarity will help clear all types of clouding
REEF AND PLANT SAFE: Clarity contains an advanced polymeric flocculating agent that is both reef and plant safe.
MULTI-USE: Clarity is the only clarifier on the market that does it all. Clarity contains both precipitating and flocculating components in the same bottle that will clear and clean all types of cloudiness in all environments.
USE: When Clarity is added to the water, you will see a cloudy haze begin to form. This should be expected and means that Clarity is beginning to work. For optimal performance, Clarity must be used in conjunction with a fine mechanical filtration media such as filter floss.
DIRECTIONS: Use 1 capful (5 mL) for every 80 L (20 US gallons). Rapid clarification will follow (1–2 hours). In the case of chemical or particulate clouding clean filter floss or cartridge after tank clears. If clouding persists, change your fine mechanical filtration media several times before dosing more clarity.
