Additional Information

• Special filtration material that selectively removes phosphate and silicate, common nutrients found in fresh and saltwater aquariums.


• In saltwater aquariums, excess phosphate lowers the available calcium and magnesium necessary for the growth of hard corals and other invertebrates.


• Will not remove trace elements or affect pH.


• Directions for use in Rena FilStar Filters:


• Remove Phos-Zorb filter pouch from plastic bag.


• DO NOT open Phos-Zorb filter pouch. One 150 g pouch should be used for every 55 U.S. gallons (208 L) of aquarium water.


• Place filter pouch in FilStar filtration basket after (above) the filter foams.


• Rinse basket under tap water for several minutes to remove dust and activate Phos-Zorb. The activation process will temporarily generate some heat in the Phos-Zorb filter pouch.


• Replace filter pouch every 1-3 months, depending on stocking density & water quality.
