The Poly-Bio-Marine Poly Filters are a formulation of a special patented material bonded to a synthetic matrix. By means of a unique proprietary process, the Poly Filter is made impervious to salt and is also organic loving to certain materials.

• 4" X 8" size
• The Poly Filter pads absorb and adsorb contaminants and other toxic materials found in nature or added to fresh and salt water with or without fish and invertebrates
• Medication added to aquariums for treatment of diseased fish will automatically be removed by the Poly Filter (after serving their intended purpose)
• It provides a supplemental means for removal of ammonia when the biological filter is unable to break down the excess ammonia and its concentration increases rapidly
• The pads are placed in any filter in a place where chemical filtration media is intended (generally, after the larger sediment has been filtered out)
• Changes color when exhausted
