The incomparable Poly FilterŪ is for filtering and purifying both fresh and salt water aquariums. It is a formulation of a special patented material bonded to a synthetic matrix. By means of a unique proprietary process, the Poly FilterŪ is made impervious to salt and is also organic loving to certain materials. It can 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 fresh and salt water aquariums for treatment of diseased fish will automatically be removed by the Poly FilterŪ after serving their intended purpose before the medication can produce a toxic effect on the fish. The Poly FilterŪ is non-toxic and harmless to biological filtration because it allows a sufficient amount of ammonia to reach the biological filter in order to sustain the bacteria culture. The Poly FilterŪ 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. Then the Poly FilterŪ adsorbs the excess ammonia while the biological filter readjusts to higher ammonia input levels. Because of this unique filtering characteristic, the Poly FilterŪ eliminates the need and expense of carbon or ion exchange resins and protein skimmers. Shipping-Weight: 0.8 lb |
