Poly Filter Pad 8" x 4"

Poly Filter has the capabilities for removing ammonia, it also removes heavy metals, harmful organics, all forms of phosphate and is without equal in the removal of medications after treatment. 

40 Parts per Billion filtration!

  • Removes all types of impurities including phosphates

  • Will not soften water of remove trace elements in solution

  • Made from a patented material

  • Used in both fresh and salt water

Poly-filter also acts as a revolutionary mechanical filter. Rather than just trapping waste, particles of debris actually cling to the Poly-Filter fibres, allowing water to flow through freely with no clogging, and ensuring no waste is released.

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. 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. Then the Poly Filter adsorbs the excess ammonia while the biological filter readjusts to higher ammonia input levels. Changes color when exhausted.

Poly-Filter Operating Instructions

Freshwater Application: Add Poly-Filter to any holder or apparatus at any time.

Establishing Marine/Reef system: Add Poly-Filter so water can pass through it. For Maximum Filtration: Eliminate all water bypass.

Poly-Filter in established marine & freshwater systems:

Conventional power filter:

  • Place Poly-Filter on bottom plate.

  • Cover with gravel or floss.

  • Do not restrict flow.

Plastic undergravel filters:

  • Place Poly-Filter on top of the undergravel plate.

  • Cover filter and plate with gravel.

Canister-type power filters:

  • Place Poly-Filter in the chemical filter compartment.

  • Add floss according to manufacturer ís instructions.

Medication removal (parasite and antibiotic treatments):

  • Remove Poly-Filter from water before any type of medication is added.

  • Follow medication instructions issued by the manufacturer.

  • After treatment is complete, place Poly-Filter back in the water to remove traces of medication.

  • Test water for safe levels.

  • When safe, remove discolored Poly-Filter, dry and save for next medication.

  • Place new Poly-Filter in the water for removal of conventional organics and water purification.

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.
