Poly Filter 4 x 8

4 x 8" Poly Filter Pad

The POLY-FILTER 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-FILTER 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-FILTER after serving their intended purpose before the medication can produce a toxic effect on the fish.

The POLY-FILTER 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-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. Then the POLY-FILTER adsorbs the excess ammonia while the biological filter readjusts to higher ammonia input levels. Changes color when exhausted.

Adding vitamins and trace elements:
Remove Poly-Filter from water before adding vitamins or trace elements. After 12 hours place Poly-Filter back into water. Poly-Filter will not remove calcium, magnesium, strontium, barium or alkalinity supplements. Poly-Filter will not remove trace elements included in marine salt mixtures.

General maintenance comments:
Poly-Filter turns color when removing medications. Aqua to Dark Blue: Copper or Copper salts. Orange: Iron. Bright Red: Aluminum. Bright Yellow: Ammonia, Amines or Solvents. Dyes: Color of the solution when added i.e. Methylene Blue: Pale Blue. Malachite Green: Light Green, Tannins/Humic acid: Dark Brown, Organic Wastes: Light Tan progressing to Dark Brown. Poly-Filter extends time between water changes. Add de-chlorinated water to make up for evaporation loss. If pH shifts below acceptable level change water and add a new Poly-Filter. Heavy slime producing water conditioners can surface coat Poly-Filter and interfere with absorption performance. In marine water, soak in 3% hydrogen peroxide then rinse (in freshwater) well. In freshwater soak in 10% marine salt water solution then rinse (in freshwater) well.
