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.
Two Sizes Available:
- 4″ x 8″
- 12″x12″
Recommended Use
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’s 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.
