Aquarium Pharmaceuticals Bio-Chem Zorb® Information

Product Manuals & Documentation

Advanced filtration material. Better than carbon alone! Convenient pouches treat up to 20 gallons.

The most scientifically-advanced filter media available. For sparkling clean water and healthy fish. Bio-Chem Zorb is a blend of 2 research-grade scavenger resins, 2 pharmaceutical-grade ion-exchange resins and high porosity activated carbon in a convenient filter pouch. Bio-Chem Zorb removes organic waste, toxic gases, water discoloration, foul odors and phenols in both fresh and saltwater, and toxic heavy metals in freshwater. Bio-Chem Zorb will not release phosphates. Treats up to 55 Gallons.

Purpose and Benefits:
  • Bio-Chem Zorb is a water filtration media comprised of research-grade organic scavenger resins, pharmaceuticals-grade ion-exchange resins and high-porosity activated carbon in a flow-through pouch. Bio-Chem Zorb removes dissolved organic pollutants from freshwater and saltwater aquariums. Bio-Chem Zorb can be used in any filter.
  • Fish, invertebrates, plants, algae and uneaten fish food release a variety of organic pollutants into the aquarium. When these pollutants accumulate in an aquarium, a stressful environment is created for all inhabitants. Poor water quality leads to lower disease resistance, inhibited growth, reduced oxygen level, discolored aquarium water and foul odors. Continuous filtration with Bio-Chem Zorb will restore water quality and create crystal clear water.
  • Bio-Chem Zorb works in freshwater aquariums by ion exchange and adsorption. Dissolved organics are adsorbed by the organic scavenger resins and activated carbon. The ion-exchange resins remove toxic heavy metals such as copper and lead. Use Bio-Chem Zorb in freshwater aquariums to keep the water healthy and sparkling clear.
  • In saltwater, Bio-Chem Zorb relies on the powerful adsorption properties of the organic scavenger resins and activated carbon. Bio-Chem Zorb is especially useful in removing refractory organics that cause yellow water, which results from a build-up of dissolved organics. These organic pollutants reduce the transmittance of blue light necessary for many marine invertebrates.
Directions for Use: Rinse the pouch thoroughly in tap water before use. Place the pouch in the aquarium filter so water passes through the pouch. Bio-Chem Zorb will remove pollutants for up to six months depending on stocking density and the level of pollutants generated in the aquarium. A heavily stocked aquarium will require more frequent replacement of Bio-Chem Zorb than a lightly stocked aquarium that receives a water change every week.

Compatibility: Bio-Chem Zorb can be used in all freshwater and marine aquariums.

Comments: Tryed the other leading brands. They don't even come close to this longest lasting mix. Keeps the water super clean and longer. Which equals to $$ saved with infrequent changes and $$ saved on replacing dead fish.

Comments: I have used Bio Chem Zorb for many years now. It lasts longer than carbon, removes more organics than carbon, and also utilizes resins. A good product that I will continue to use for the life of my reef tank.

Comments: Forget those other products. Bio Chem Zorb is by far superior.One 10oz. pouch lasts 6 months in out 30g long aquarium. Which is stocked with freshwater to capacity. Angels, Tetras, algae eater. Just rinse the pouch out 2 to 3 times during that 6 month period. No smelly water. We have been using this product for 14 years. Replace in 6 months rinse and repeat. What can be simpler? Yes I have tried other brands during this period that "claimed" to last up to 6 months. Those didn't make it 3 months before they had to be thrown away.And don't bother with those 30 day pouched with just carbon in them. They are a total waste of money.
