Boyd Chemi Pure 5 oz

  • Quickly filters excess waste nutrients that bacteria feed on, stopping bacteria build-up
  • LONGER LIFE – Fish often live 3 to 4 times longer
  • CONSTANT pH – Always within the safe range

Chemi-pure remains a revolutionary product for over 60 years, and practically all aquarium filter media have been modeled after it! Large aquariums or small, Chemi-pure produces consistent results that make it easier to maintain a beautiful and healthy aquarium.

Chemi-pure can be used with all water types as a chemical absorption filter, ion generator, and exchange unit to positively keep pH at a perfect and constant level. Chemi-pure is also fantastic for use with African cichlids and Discus! Chemi-pure does not remove trace elements and is the only filter medium that aids in the natural balance of positive and negative charges, with an emphasis on the beneficial negative ion. Now featuring QuickWash Carbon™, our newest improvement to the original Chemi-pure formula. This carbon is pelletized and pre-washed providing the best combination of surface area, pore size, and dust content, making it the ideal filtration solution for fresh and saltwater aquariums.
