Seachem Purigen is a great addition to your filter media.

Seachem Purigen absorbs nitrogenous compounds and changes colour as it exhausts. Once exhausted it can be regenerated or replaced.

Think of Seachem Purigen as a far more capable ‘Active Carbon filter insert’.

Description

  • Highest organic removal capacity
  • Helps control ammonia/nitrite/nitrate
  • Colour changes as it exhausts; easily regenerated

 

Directions:

 

Rinse before use. Use in a fine mesh (180 micron or less) filter bag such as Seachem’s The Bag.

For best results, Purigen should be placed so as to maximize the flow of water through it. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter.

Each 250 mL treats up to 1,000 L (250 US gallons) for up to six months. Exhaustion is indicated by a pronounced discolouration of the beads to dark brown or black.

Regeneration Soak in a 1:1 bleach: water solution for 24 hours in a non-metallic container in a well-ventilated area and away from children. Use regular 8.25% hypochlorite household bleach (non-scented, no dyes, do not use a splash-less bleach).

Rinse well, then soak for 8 hours with a solution containing 4 tablespoons of Prime, or equivalent dechlorinator per cup of water. Rinse well.

For freshwater use, soak for 4 hours with a solution containing 2 tablespoons of buffer per cup of water ( Discus Buffer, Neutral Regulator ).

Original colour and full activity should now be restored and Purigen is ready for reuse. Caution: some slime coat products may permanently foul Purigen and render regeneration difficult. Do not reuse if the odour of bleach/chlorine is detectable.

In case of doubt, soak beads in a small quantity of water and test for residual chlorine with a chlorine test kit.
