Poly-Bio-Marine: 4x8" Poly Filter Pad

Filter + purify both fresh and salt water aquariums with this 4x8" poly-filter pad from Poly-Bio-Marine Inc. It is a formulation of a special patented material bonded to a synthetic matrix. 

It 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. This poly-filter 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; thereby, adsorbing any excess ammonia while the biological filter readjusts to higher ammonia input levels.

Notice:

Be AWARE that any Medication added to fresh and saltwater aquariums for treatment of diseased fish will automatically be removed by the poly-filter. Feel free to to install this filter post treatment. It is suggested to do so after the poly-filter has served its  intended purpose to avoid the chance of your fish being exposed to any toxins left over the medication(s).
