Our take on the Brightwell Purit

Brightwell Purit is a mixed filtration media for aquariums: activated carbon plus ion-exchange and adsorption resins in a mesh bag. It targets discoloration, odors from decaying organics, copper from medicated systems, and nutrients such as ammonia, nitrate, phosphate and silicate. It works in freshwater, saltwater and reef tanks. The best new price is $58.38 at Amazon as of November 4, 2026, with two stores listing it new.
