Seachem Purigen Filtration Resin – Organic Removal Media for Lobster Tanks and Seafood Display Systems

Seachem Purigen is a high-capacity filtration resin designed to remove dissolved organic waste from lobster tanks before it breaks down into ammonia. This helps stabilize water conditions and prevent cloudy water, odor, and water quality issues.

In supermarket, seafood market, and restaurant lobster tank systems, organic waste builds quickly from livestock and feeding. Purigen removes this waste at the source, improving clarity and reducing strain on the rest of the filtration system.

This is one of the most effective ways to control water quality before problems start, rather than reacting after the tank turns cloudy or unstable.

Purigen works differently than mechanical filters or carbon. While pads catch debris and carbon removes some contaminants, dissolved organic waste can still circulate through the system. Purigen targets that waste directly.

In real-world service work, this is often added when:
tanks keep going cloudy even after pad changes
ammonia issues keep returning
systems are heavily stocked or fed frequently

It is commonly used as a “stabilizer” media to reduce recurring water quality problems in live lobster tank systems.

Fits most standard filter boxes used in Stark, Marineland, and Lobster Life lobster tank systems. Confirm dimensions and orientation before installation.

Place Purigen inside a media bag and position it in a high-flow area of the filtration system.

Make sure water is consistently passing through the media, not around it.

Monitor the color of the resin. As it darkens, it is becoming exhausted and should be regenerated or replaced.

Do not allow the media to dry out during use.
Always place in a strong flow area for proper effectiveness.

If your tank is already cloudy or unstable, combine with:
fresh filter pads
partial water change
bacteria support if needed
Follow manufacturer regeneration instructions carefully before reuse.
