Experience exceptionally clear aquarium water with Seachem Purigen, a premium synthetic filtration resin that removes dissolved and insoluble organic waste before it can break down into ammonia, nitrite and nitrate.
Purigen offers excellent organic-removal capacity and helps improve water clarity without significantly affecting essential trace elements. As the media becomes exhausted, it changes from a pale blonde color to dark brown or nearly black, making it easy to monitor.
Unlike many disposable filter media products, Purigen can be regenerated and reused when Seachem’s official regeneration instructions are carefully followed.
Available Sizes
250 mL
Treats up to 250 gallons for up to six months.
500 mL
Treats up to 500 gallons for up to six months.
Actual service life may vary depending on aquarium stocking levels, feeding habits and the amount of organic waste present.
Key Features
• Produces exceptionally clear aquarium water
• Removes dissolved and insoluble organic waste
• Helps control the buildup of ammonia, nitrite and nitrate

• Changes color as it becomes exhausted

Directions
Rinse thoroughly before use.
Place Purigen inside a fine-mesh filter bag rated at 180 microns or finer, such as Seachem The Bag. Position the media in an area where water will flow directly through it.
Purigen is exhausted when the resin becomes dark brown or nearly black. At that point, it may be regenerated by carefully following Seachem’s official regeneration instructions.
Never return regenerated Purigen to an aquarium if any chlorine or bleach odor remains.
Important
The 250 mL and 500 mL containers include loose filtration media. A suitable fine-mesh media bag is required and sold separately.
