Seachem Clarity

Clarity™ is a versatile water clarifier designed for both freshwater and marine aquariums. Using a specially formulated polymeric flocculant, it binds tiny particles that cause cloudiness, making it easier to remove them through mechanical filtration. Safe for reefs, plants, and all aquatic life, Clarity™ simplifies water clarification by addressing all types of cloudiness in a single, easy-to-use product.

The Science

When you add Clarity™ to your aquarium, you will notice the water developing a cloudy haze shortly after dosing. This is completely normal and is actually a sign that the product is working. Your water contains vast numbers of microscopic particles — fine debris, dissolved organics, and suspended matter — that are too small to be caught by filter media or even seen with the naked eye. Clarity™ causes these particles to bind together through a process called flocculation, gradually forming larger and larger clumps.

As those clumps grow in size, they become visible, which is what causes the temporary increase in cloudiness you may observe after dosing. Once the particles have aggregated into pieces large enough to be captured by mechanical filtration, your filter floss or cartridge does the rest, physically removing the residue from the water. The result is noticeably clearer water within 1 to 2 hours in most situations. For Clarity™ to work effectively, your aquarium must have a filter with mechanical filtration media such as filter floss running throughout the process.
