Bio-Chem Zorb is composed of two organic scavenger resins and two ion-exchange resins, combined with a high-porosity activated carbon. Together, they remove synthetic chemicals, naturally occurring organic pollutants and metabolic by-products from aquarium water. Bio-Chem Zorb filters water to a level not achievable with carbon alone.

Organic Pollutants in the Aquarium: Bacterial decomposition of dead fish and plants, uneaten fish food and solid waste from fish and invertebrates creates organic pollutants in the aquarium. In nature, water currents and tides carry these pollutants away. Aquarium water, however, is changed only periodically. In between changes, organic pollutants can accumulate to harmful levels.

Effect of Accumulated Organic Pollutants in the Aquarium:

The accumulation of organic pollutants creates a stressful environment and provides a breeding ground for fish pathogens. Some naturally occurring bacteria break down certain organic pollutants. However, this action is often incomplete in an aquarium and uses up oxygen, reducing the amount of oxygen available for fish, invertebrates and the biological filter.

Poor water quality ultimately causes suppression of the immune system, leading to disease outbreaks and inhibiting the growth and reproduction of fish and invertebrates. The accumulation of organic pollutants also leads to negative effects such as decreased pH, discolored water, reduced light transmittance and foul odors.

Bio-Chem Zorb cleans aquarium water through ion exchange, adsorption and absorption processes. Organic pollutants, toxic heavy metals and aquarium medications are efficiently \"sorbed\" by organic scavenger resins and high-porosity activated carbon in Bio-Chem Zorb.

Using Bio-Chem Zorb In Salt Water: Bio-Chem Zorb is especially useful in removing refractory organics or \"yellow water\" that form when organic pollutants are not biodegraded. These organic pollutants can reduce the transmittance of light energy necessary for many saltwater invertebrates. With Bio-Chem Zorb, a high redox potential will be easier to maintain. Bio-Chem Zorb is also very effective for removing aquarium medications and treatments.
