Purigen 250ml

Purigen is a filter resin for keepers of marine and freshwater aquariums who want to reduce the organic load in their systems. It is supplied in a 250 ml pack and goes into a fine-mesh filter bag inside the filter, which makes it a practical addition to an existing filtration setup.

Why it matters

• The resin is designed to capture organic contaminants as well as dissolved ones, unlike products that contain only ion exchangers.
• Its granules are porous rather than smooth, which increases the contact surface with the water and the amount of waste it can hold.
• According to the manufacturer, it targets large nitrogen-containing molecules, mainly from fish and invertebrate waste and decaying plant material, rather than simple molecules.
• When spent, the granules darken from light tan through dark brown to nearly black, so the change in colour indicates when the media needs replacing or regenerating.

What it works with

Purigen is intended for both marine and freshwater aquariums and is used as filter media alongside mechanical and biological filtration. The usage guideline of about 4,000 litres per litre of resin is a reference for planning the amount needed for the size of the tank.
