The API BIO-CHEM ZORB contains a superior blend of resins and activated carbon that removes impurities from the aquarium, such as colors, odors, heavy metals, and toxic gases. The filtration media makes the aquarium water crystal clear.

It also removes impurities that block light, promoting enhanced coral growth in saltwater and plant growth in freshwater aquariums.

Instructions:

• Rinse the cartridge under tap water to remove loose dust. The cartridge does not need to be rinsed completely.
• Place the cartridge in the water flow path in the aquarium filter.
• Replace every 2 months or sooner if the aquarium is heavily stocked and/or colors or odors are detected.

Use it when starting up or maintaining an aquarium, or if impurities are detected.
